Strong’s G4644: A compound adjective meaning “stiff-necked,” combining “hard” (sklēros) and “neck” (trachēlos). Used metaphorically to describe stubborn resistance to God’s will. Specifically echoes Old Testament language about Israel’s rebelliousness, emphasizing willful disobedience.

U- Unveiling the Word

Σκληροτράχηλος represents a powerful metaphor drawn from agricultural imagery of unruly oxen refusing the yoke. In Stephen’s speech (Acts 7:51), it carries the weight of centuries of prophetic rebuke, connecting his audience’s resistance to the Holy Spirit with Israel’s historic pattern of rebellion. Early church fathers used this term to discuss the nature of human rebellion against divine authority and the need for spiritual submission. Today, it continues to illustrate how pride and stubbornness can manifest in resistance to God’s leading.
