THE OIL FOR THE LAMP.

(20) Thou shalt command the children of Israel that they bring thee pure olive oil.--This instruction had been already given (Exodus 25:2; Exodus 25:6), only not with such particularity. "Oil" had been required, but not "pure olive oil beaten." By this is meant the best possible olive oil--that which was obtained by "beating," or pounding in a mortar; which was free from various impurities that belonged to the oil crushed out, after the ordinary fashion, in a mill.

To cause the lamp to burn always--i.e., every night without intermission. Josephus says that three lights were kept burning both night and day (Ant. Jud., iii. 7, ? 7); but there is nothing in Scripture to confirm this. The tabernacle would have received sufficient light during the daytime through the entrance curtain, which was of linen (Exodus 26:36), not to mention that the curtain may, when necessary, have been looped up. The lighting of the lamps every evening is distinctly asserted in Exodus 30:8; their extinction in the morning appears from 1Samuel 3:3.

Verses 20, 21. - THE OIL FOR THE LAMP. It has been observed that this paragraph is somewhat out of place. It would more appro priately, according to human ideas, have terminated ch. 25. But "God's ways are not as man's ways, nor his thoughts as man's thoughts." It is frequently difficult - some-times impossible - for the keenest human intellect to trace the connecting links between one portion of God's word and the next. In such cases it is best not to speculate on the nature of the connection, but to content ourselves with laying to heart the lesson which each portion teaches separately. Verse 20. - Thou shalt command. Compare Exodus 25:6, where the general command had been given. Here certain additions are made as to the quality of the oil which was to be brought. The oil was to be pure olive oil beaten that is to say, it was to be olive oil purified from any admixture of that watery juice which the Romans called amurca; and it was to be of the kind which is obtained by mere beating or pounding in a mortar, and not by crushing in a mill. Oil of this kind, which is usually made from the unripe fruit, is reckoned much the best; it is clear and colourless, and gives a bright pure light with little smoke. To cause the lamp to burn always. It has been supposed from this expression that the lamp must have been kept constantly burning both day and night; and Josephus declares that this was actually so, at least with three out of the seven lights (Ant. Jud. 3:7, 7). But there are several places m Scripture which state, or imply, the contrary. (See especially Exodus 30:8; and 1 Samuel 3:3.) It seems to have been the duty of the high-priest to light the lamps every evening, and to give them a sufficient supply of oil to last till daybreak, at which time "the lamp of God went out" (1 Samuel l.s.c.) The supposition that "one light at least was always burning" (Kalisch), because no daylight could penetrate into the structure through the fourfold covering, ignores the fact that light would enter through the single curtain at the entrance, as well as the probability that some portion of that curtain may generally have been looped up. If we regard the lamp as extinguished during the daytime, we must understand "always" here to mean "regularly every night."

27:20,21 The pure oil signified the gifts and graces of the Spirit, which all believers receive from Christ, the good Olive, and without which our light cannot shine before men. The priests were to light the lamps, and tend them. It is the work of ministers, by preaching and expounding the Scriptures, which are as a lamp, to enlighten the church, God's tabernacle upon earth. Blessed be God, this light is not now confined to the Jewish tabernacle, but is a light to lighten the gentiles, and for salvation unto the ends of the earth.And thou shall command the children of Israel,.... Here begins a new section of the law; an account being given of the tabernacle, and its parts, and the furniture thereof, next the several parts of service done in it are observed; and the account begins with that of the candlestick in the holy place, in order to which Moses is directed to command the people of Israel, whose business it was to provide for it:

that they bring thee pure oil olive beaten for the light; for the light of the candlestick, to light up the several lamps in the several branches of it; and the oil to be brought and used there was not any sort of oil, as what is got out of fishes, as train oil, or out of nuts, as oil of almonds, but what comes from the olive tree; and this must be pure and free from lees and dregs, and must be beaten with a pestle in a mortar, and not ground in a mill, that so it might be quite clear; for being bruised and beaten, only the pulp or flesh of the olive was broken, but being ground in a mill, the stones were broken and ground, and so the oil not so pure.Jarchi and Ben Melech, from their Rabbins, observe, that after the first drop was pressed out, they put them into mills and grind them; but then, though the oil was fit for offerings, it was not fit for the light of the candlestick. Ben Gersom says, they put the olives bruised into a basket, and the oil dropped from them without pressing at all; and this was the choicest and most excellent for the light. The quantity to be brought is not fixed; but the measure fixed by the wise men of Israel, as Jarchi says, was half a log, that is, for every lamp; and this was the measure for the longest nights, the nights of the month Tebet, and so the same for all other nights:

to cause the lamp to burn always night and day, continually, as it was proper it should, that the house of God might not be at any time in darkness; as it would otherwise be, since there were no windows in it; and his servants minister in it in the dark, even in the daytime, at the altar of incense, and at the shewbread table, which is not reasonable to suppose; and though there are some passages of Scripture which seem to intimate as though the lamps only burnt till the morning, and then went out, and were lighted every evening; this difficulty may be solved, and the matter reconciled by what Josephus (l) relates, who must be an eyewitness of it, that three of the lamps burned before the Lord in the daytime, and the rest were lighted at the evening; and Hecataeus (m), an Heathen writer, speaking of the golden candlestick, says, its light was unextinguished day and night, particularly the lamp which was in the middle; also the candlestick is by the ancient Jews, and by Nachmanides, said to have been never extinct.
