Most English Bibles can't carry the full weight of what's in the original Hebrew and Greek. The F.O.G Bible Project exists to change that — three new translations built publicly (a Study Bible, a Reader's Bible, and F.O.G Jr. for younger readers), plus a word-by-word renewal of Strong's Concordance restoring the depths most translations leave behind. It is Jean Paul's lifelong work, unfolding in public — and you're invited in.
Jean Paul Joseph is the lead editor of the F.O.G Bible Project. He works from a personal encounter with Jesus first, then draws on the scholarship of respected Jewish and Christian scholars — because the church was Jewish before it was anything else, and those roots change everything about how you read Scripture.

The Lie That Cannot Stand Before the Light
Thirteen times the Holy Spirit breathes this word into the New Testament—pseúdomai, the verb of falsehood, the act of bending truth until it breaks. Yet even in its first appearing, the lie is already defeated. In Matthew chapter five, the Lord Yeshua speaks of those who came before Him, the prophets who were persecuted, and He says: “Rejoice and be glad, for great is your reward in heaven, for so they persecuted the prophets who were before you.” And then He warns against those who would pseúdomai—who would speak falsely against His disciples. The first utterance of this verb in the New Testament is not about a lie told in secret, but about a lie spoken against the righteous. Already the pattern is set: the lie is an assault upon the truth-bearer, and the truth-bearer is the one who stands in the lineage of the prophets. You cannot utter falsehood without first choosing whom you will oppose.
The Grammar of Deception: Middle Voice and the Self-Wrapped Lie
The grammarians among the Greeks knew something the philosophers only glimpsed: the middle voice of a verb reveals the soul’s posture. When a man says pseúdomai, he is not merely performing an action—he is acting upon himself. The middle voice means the liar is both the subject and the object of his own falsehood. He speaks a lie, and in that very speaking, he wraps himself in the lie. The ancient sages observed that a man who speaks falsely does not merely deceive others; he first deceives his own heart. The apostle Paul, writing to the Romans, declares that every man is a liar—pseústēs—but God remains true (Romans 3:4). The grammatical form of this verb, always middle or passive in the New Testament, teaches you something profound: no one is forced to lie. The lie is a choice that bends back upon the chooser. The aorist tense, when it appears, captures the moment of decision—a single, completed act of falsehood that stains the soul. But the present tense, used by the apostle John in his first letter, shows the habitual liar: “If we say we have fellowship with Him while we walk in darkness, we pseúdomai—we lie—and do not practice the truth” (1 John 1:6). The tense reveals the condition of the heart.
The Septuagint Bridge: When Greek Meets Hebrew
When the seventy elders translated the Hebrew Scriptures into Greek, they chose pseúdomai to carry the weight of a Hebrew word that trembles with moral failure: kachash, meaning to deceive, to deny, to fail. In the book of Leviticus, the Lord commands His people: “You shall not steal, nor pseúdomai—you shall not lie—nor deal falsely with one another” (Leviticus 19:11). Here the Greek verb translates the Hebrew shakhar, the act of breaking faith through falsehood. The Septuagint reveals that lying is never a private matter—it is a breach of covenant, a wound in the community of Israel. When the prophet Hosea cries out against the land, he says there is no truth, no mercy, no knowledge of God—only swearing, lying (pseúdomai), killing, stealing, and adultery (Hosea 4:1-2). The Hebrew behind this Greek verb is kachash, which also carries the sense of failing under pressure, of shrinking back from truth when the cost is high. The rabbis of old taught that the first lie ever spoken was not against another human, but against God Himself—when Adam said, “I was afraid because I was naked, and I hid myself.” The lie began as a cover, and every lie since has been a garment woven to hide the soul from the Light.
The Apostolic War Against Falsehood
The apostle Paul, more than any other New Testament writer, wages war against pseúdomai. In his letter to the Colossians, he commands: “Do not pseúdomai to one another, seeing that you have put off the old man with his practices” (Colossians 3:9). Here the verb appears in the present imperative with a negative—a command to stop an action already in progress. Paul knows that the old nature clings to falsehood like a garment that will not be removed. But he also knows something deeper: the lie is not merely a sin; it is a symptom of a divided heart. In Ephesians, he writes that we must “speak truth, each one with his neighbor, for we are members of one another” (Ephesians 4:25). The opposite of pseúdomai is not merely accuracy—it is alētheia, truth as reality, as the very substance of God. The early church understood that lying was not just forbidden; it was impossible for those who had been born from above. Ignatius of Antioch, writing to the Ephesians, declared that the Christian speaks truth not because he fears punishment, but because he has been united to the Truth Himself. The apostolic tradition teaches that lying is a return to the chaos from which the Word called forth creation.

The Narrative of the Lie Exposed
In the book of Acts, a story unfolds that reveals the terrible weight of pseúdomai. Ananias and Sapphira, husband and wife, sell a piece of property and bring part of the price to the apostles’ feet—but they keep back some for themselves, and they say the whole amount is there. Peter looks at Ananias and speaks words that echo through the centuries: “Why has Satan filled your heart to pseúdomai—to lie—to the Holy Spirit?” (Acts 5:3). Notice the grammar: the verb is in the aorist infinitive, capturing the completed act of deception. But Peter goes further: “You have not lied to men, but to God.” The lie, though spoken in the presence of the apostles, was heard in the throne room of heaven. The narrative does not end with a rebuke; it ends with a death. The early church understood that the lie was not merely a social failing—it was an assault upon the Spirit who is Truth. The fathers of the faith observed that Ananias and Sapphira did not die because they kept back money; they died because they attempted to deceive the One who searches hearts. The lie, when aimed at God, is a weapon that shatters in the hand of the one who wields it.
The Messianic Fulfillment: Yeshua, the Truth Who Cannot Lie
The New Testament writers apply the word pseúdomai to every human mouth, but never to the mouth of Yeshua. He is the One who says, “I am the way, and the truth, and the life” (John 14:6). The apostle Paul, writing to Titus, declares that “God, who cannot pseúdomai—who cannot lie—promised eternal life before the ages began” (Titus 1:2). The verb appears in the infinitive, describing an impossibility: it is not that God chooses not to lie; it is that lying is contrary to His very nature. The author of Hebrews echoes this truth: “It is impossible for God to lie” (Hebrews 6:18). If Yeshua is the Word made flesh, then He is the utterance of the Father, and the Father cannot speak falsehood. Every word that proceeds from His mouth is truth, even when the truth is hard. When Pilate asks, “What is truth?” he stands before the Answer and does not recognize Him. The Messianic fulfillment of pseúdomai is not that Yeshua avoids lying—it is that He is the end of all falsehood, the One in whom the shadow of deception has no place. The early church confessed that in Christ, the old lie of the serpent is undone, and the new creation speaks only what is true.
The Lie That Cannot Stand Before the Throne
In the final vision of the apostle John, the Holy City descends from heaven, and those who enter are described in stark terms: “Outside are the dogs, and the sorcerers, and the fornicators, and the murderers, and the idolaters, and everyone who loves and practices pseúdomai—falsehood” (Revelation 22:15). The verb here is in the present participle, describing a way of life, a habitual practice of deception. The lie cannot enter the city because the city is filled with the light of the Lamb, and in that light, all falsehood evaporates. The rabbis of old taught that the seal of the Holy One is truth—the Hebrew word emet, which contains the first, middle, and last letters of the alphabet, signifying that truth encompasses all things. The lie, by contrast, has no lasting substance; it is a vapor that vanishes when the sun rises. The apostolic faith teaches that the final judgment is not a test of knowledge but a revelation of reality: every lie is exposed, every deception stripped away, and only what is true remains.
Your Mouth, Your Heart, Your Call to Truth
You stand at the crossroads of every word you speak. Before you utter a syllable, the choice is already made: will you speak the truth, or will you pseúdomai? The middle voice of this verb reminds you that every lie bends back upon your own soul, wrapping you in a garment of darkness. But the voice of the Truth Himself calls you out of the shadow. You cannot serve the God of truth with a divided tongue. The apostle James wrote that from the same mouth come blessing and cursing—this should not be so. Let your yes be yes, and your no be no, for whatever is more than these comes from the evil one. The Holy Spirit, who is the Spirit of truth, dwells within you, and He cannot bear false witness. When you speak, heaven listens. When you lie, heaven grieves. But when you speak truth, even in the smallest matter, you join the chorus of the redeemed who stand before the throne and declare: “Holy, holy, holy is the Lord God Almighty, who was and who is and who is to come.” The lie cannot stand before that light. So let your words be few, your heart be pure, and your tongue be the vessel of the One who cannot lie. May the God of truth guard your lips, and may the Messiah who is the Truth Himself dwell in your mouth forever.
