light upon the side opposite to the front of the candlestick. In itself, therefore, there is nothing at all striking in the renewal and explanation of those directions, which committed the task of lighting the lamps to Aaron; for this had not been done before, as Exo 27:21 merely assigns the daily preparation of the candlestick to Aaron and his sons; and their being placed in the connection in which we find them may be explained from the signification of the seven lamps in relation to the dwelling of God, viz., as indicating that Israel was thereby to be represented perpetually before the Lord as a people causing its light to shine in the darkness of this world. And when Aaron is commanded to attend to the lighting of the candlestick, so that it may light up the dwelling, in these special instructions the entire fulfilment of his service in the dwelling is enforced upon him as a duty. In this respect the instructions themselves, coupled with the statement of the fact that Aaron had fulfilled them, stand quite appropriately between the account of what the tribe-princes had done for the consecration of the altar service as representatives of the congregation, and the account of the solemn inauguration of the Levites in their service in the sanctuary. The repetition on this occasion (Exo 27:4) of an allusion to the artistic character of the candlestick, which had been made according to the pattern seen by Moses in the mount (Exo 25:31.), is quite in keeping with the antiquated style of narrative adopted in these books.

Num 8:5-7 Consecration of the Levites for their service in the sanctuary. - The choice of the Levites for service in the sanctuary, in the place of the first-born of the people generally, has been already noticed in Num 3:5., and the duties binding upon them in Num 4:4. But before entering upon their duties they were to be consecrated to the work, and then formally handed over to the priests. This consecration is commanded in Num 8:7., and is not called קדּשׁ, like the consecration of the priests (Exo 29:1; Lev 8:11), but טהר to cleanse. It consisted in sprinkling them with sin-water, shaving off the whole of the hair from their bodies, and washing their clothes, accompanied by a sacrificial ceremony, by which they were presented symbolically to the Lord as a sacrifice for His service. The first part of this ceremony had reference to outward purification, and represented cleansing from the defilement of sin; hence the performance of it is called התחטּא (to cleanse from sin) in Num 8:21. “Sprinkle sin-water upon them.” The words are addressed to Moses,
