Numbers 8:11
offer <05130> [offer. Heb. wave. offering. Heb. wave-offering.]
Not that they were actually waved, but they were presented to God, as the God of heaven, and the Lord of the whole earth, as the wave offerings were; and in calling them wave-offerings, it was intimated to them that they must move to and fro with readiness in the business of their profession.
they may <05647> [they may execute. Heb. they may be to execute, etc.]
Numbers 8:13
then offer them .... wave offering <05130 08573> [offer them.]
{Wehainaphta othom tenoophath,} literlly, as in ver. 11, "and thou shalt wave them for a wave-offering;" manifestly in allusion to the ancient sacrificial rite of waving the sacrifices before the Lord; and it is probable, that some significant action, analogous to the waving of the sacrifice, was employed on this occasion; for the Levites were considered as an offering to the Lord, to whose service they were wholly dedicated. To this the apostle Paul manifestly alludes, when, in writing to the Romans, he says, (ch. 12:1,) "I beseech you, therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service."
Numbers 3:12
When God miraculously destroyed all the first-born of the Egyptians, (Ex 12:29,) he spared those of the Israelites; and, in commemoration of that event, he was pleased to appoint that all the first-born males "should be set apart unto himself." (Ex 13:12-16.) God is here pleased to relinquish this claim, and to appoint the whole tribe of Levi to attend his immediate service in their stead.
