Numbers 8:13 Meaning and Commentary

Numbers 8:13

And thou shalt set the Levites before Aaron, and before his
sons
After atonement was made for them, as Aben Ezra observes; then they were presented to Aaron and his sons, to whom they were given to he their ministers, and assistants to them:

and offer them [for] an offering unto the Lord:
or, and "waved them", &c. as before, that is, order them to be waved; for not Moses, but Aaron, did this, and indeed was done already; and therefore should rather be rendered, as by Bishop Patrick, after thou hast offered, or waved them.

Numbers 8:13 In-Context

11 and Aaron hath waved the Levites -- a wave-offering before Jehovah, from the sons of Israel, and they have been -- for doing the service of Jehovah.
12 `And the Levites lay their hands on the head of the bullocks, and make thou the one a sin-offering, and the one a burnt-offering to Jehovah, to atone for the Levites,
13 and thou hast caused the Levites to stand before Aaron, and before his sons, and hast waved them -- a wave-offering to Jehovah;
14 and thou hast separated the Levites from the midst of the sons of Israel, and the Levites have become Mine;
15 and afterwards do the Levites come in to serve the tent of meeting, and thou hast cleansed them, and hast waved them -- a wave-offering.
