Studying Lexicon Insights

In the New Testament, λύχνος is often used in the context of teachings about light, both literal and metaphorical. Matthew 5:15 encourages believers not to hide their “lamp” (λύχνος) but to place it where it can illuminate their surroundings, symbolizing how faith should be lived out openly. Similarly, in Revelation 22:5, the imagery of light is associated with the eternal illumination provided by God, where there is no need for a physical lamp because the Lord Himself provides the light.

In classical Greek literature, λύχνος was commonly used to describe everyday oil lamps used in homes, temples, and public spaces. It was an essential object in a time without electricity, and its presence in the household was vital for daily life. This makes its metaphorical use in the New Testament even more poignant, as light was not something taken for granted, but necessary for both survival and spiritual growth.
