Exo 27:20-21 | KD | STEP | The sons of Israel were to bring to Moses (lit., fetch to thee) olive oil, pure (i.e., prepared from olives “which had been cleansed from leaves, twigs, dust, etc., before they were crushed”), beaten , i.e., obtained not by crushing in oil-presses, but by beating, when the oil which flows out by itself is of the finest quality and a white colour. This oil was to be “for the candlestick to set up a continual light.”

‏ Exodus 27:20-21

The sons of Israel were to bring to Moses (lit., fetch to thee) olive oil, pure (i.e., prepared from olives “which had been cleansed from leaves, twigs, dust, etc., before they were crushed”), beaten, i.e., obtained not by crushing in oil-presses, but by beating, when the oil which flows out by itself is of the finest quality and a white colour. This oil was to be “for the candlestick to set up a continual light.” Exo 27:21

Aaron and his sons were to prepare this light in the tabernacle outside the curtain, which was over the testimony (i.e., which covered or concealed it), from evening to morning, before Jehovah. “The tabernacle of the congregation,” lit., tent of assembly: this expression is applied to the sanctuary for the first time in the preset passage, but it afterwards became the usual appellation, and accords both with its structure and design, as it was a tent in style, and was set apart as the place where Jehovah would meet with the Israelites and commune with them (Exo 25:22). The ordering of the light from evening to morning consisted, according to Exo 30:7-8, and Lev 24:3-4, in placing the lamps upon the candlestick in the evening and lighting them, that they might give light through the night, and then cleaning them in the morning and filling them with fresh oil. The words “a statute for ever unto their generations (see at Exo 12:14) on the part of the children of Israel,” are to be understood as referring not merely to the gift of oil to be made by the Israelites for all time, but to the preparation of the light, which was to be regarded as of perpetual obligation and worth. “For ever,” in the same sense as in Gen 17:7 and Gen 17:13.
