📖 Biblical Definition
The oil lamp was the small clay or metal vessel that held olive oil and a wick — the household’s primary light after sundown for most of biblical history. Scripture freights it with theological weight. The lamp of David that would not be quenched (1 Kings 11:36; 15:4; 2 Kings 8:19) — the covenantal promise of an unending Davidic line. The five wise virgins’ lamps with oil ready, contrasted with the foolish whose oil ran out (Matthew 25:1-13). "The light of the body is the eye" (Matthew 6:22), with the lamp of the body as the figure. And the new Jerusalem: "the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof" (Revelation 21:23).

Webster: lamp — “a vessel for containing oil to be burned by means of a wick.”
Israelite household lamps were small open clay dishes or pinched-rim vessels burning olive oil; the wick was twisted flax. They burned for hours but required regular oil and trimmed wicks — the Bible's most pervasive picture of the daily care of the soul.
📖 Key Scripture
Psalm 119:105 — "Thy word is a lamp unto my feet, and a light unto my path."
Matthew 25:8 — "Give us of your oil; for our lamps are gone out."
Matthew 6:22 — "The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light."
Revelation 21:23 — "And the city had no need of the sun... for the glory of God did lighten it, and the Lamb is the light thereof."
⚠️ Modern Corruption
Modern light is free; the daily-tending picture of the oil lamp — oil supply, trimmed wick, conserved fuel — has been lost from Christian imagination.

Matthew 25 only works if oil is finite and lamps go out. The wise virgins did not feel more spiritual than the foolish; they had simply tended their lamps. Their oil was bought ahead of time.
We live with constant ambient light and forget. Recover the picture — lamp, wick, oil, trimming — and verses across both Testaments come back to life. The household needs tendable light, not just bright light.
🔗 Greek & Hebrew Roots
Hebrew names the lamp itself, and the New Testament uses both the small household lamp and the larger torch.

H5216 — נֵר (ner) — lamp; David's preserved ‘lamp’ (1 Kings 11:36) and the household's nightly light.
Note: Greek luchnos is the small household lamp; lampas is the larger torch — both are in Matthew 25, depending on translation.
Usage
"Buy the oil before the cry goes up at midnight."
"Trim the wick before you complain about the dim light."
"The household with daily-trimmed lamps will not be caught dark."
