Numbers 16:7

And put fire therein, and put incense in them before the LORD to morrow: and it shall be that the man whom the LORD doth choose, he shall be holy: ye take too much upon you, ye sons of Levi.

And put fire therein,.... Into the censers:

and put incense in them; on the coals of fire in the censers:

before the LORD; not at the altar of incense in the holy place, into which none but Aaron and his sons might come, but at the door of the tabernacle of the congregation, where the glory of the Lord appeared,

Numbers 16:18; and this they were to do

tomorrow; the day following that on which the insurrection was made, and in the morning of that day, which was the usual time of judgment; this was delayed until the morrow, that they might have opportunity to reflect upon what they had done, and repent of their sin, and consider what they were to do, and the danger which might attend it; as in the case of Nadab and Abihu, who, though sons of the high priest, yet offering strange fire, were consumed by fire, Numbers 10:1; and so might they for assuming the priesthood, and officiating in any part of it, which did not belong to them:

and it shall be, that the man whom the Lord doth choose, he shall be holy: meaning Aaron, with his sons; for though the Lord had already chosen him, and ordered him and his family to be separated from the rest of the Israelites, to exercise the priestly office, and he was actually invested with it, and had entered upon it; yet he would at this time, in a visible way and manner, make it manifest that he had done it, and therefore should be as it were afresh set apart for holy service, and be continued in it:

ye take too much upon you, ye sons of Levi: of which tribe Korah was; and it looks as if those with him were chiefly of that tribe; however, these here addressed certainly were, and Moses retorts their own language upon them; they had said, that he and Aaron had taken too much upon them, though no more than what God had called them to; and now he says that they had taken too much upon them, to resist the ordinance of God, and to endeavour to remove from their office whom God had put into it, in order to substitute themselves: or "it is enough for you", or "let it suffice you"; be content with the honour put upon you, the dignity you are raised to, to be next to the priests, and assistants to them; be not ambitious of more; let what you have satisfy you.
