Numbers 32:21 Meaning and Commentary

Numbers 32:21

And will go all of you armed over Jordan before the Lord
Moses tries them thoroughly, and is very express in his words, requiring them not only to go armed, or march from the place where they were, towards the land of Canaan, but to go over Jordan, and not some of them only, but all, and that before the Lord; though indeed, when the tribes came to the river Jordan, the ark, which was the symbol of the divine Presence, went before all the tribes into it, and there stayed till they passed over, and then these two tribes and the half tribe of Manasseh passed before the children of Israel, and before the Lord, unto battle, ( Joshua 3:11 Joshua 3:17 ) ( Joshua 4:12 Joshua 4:13 )

until he hath driven out his enemies before him:
the Canaanites, who were the enemies of the Lord, as well as of his people; and because of their sins, in which they showed their enmity to God, the land spewed them out, and he drove them out to make way for his people Israel, and till this was done the tribes of Reuben and Gad were to continue with them.

Numbers 32:21 In-Context

19 And we will not any longer inherit with them from the other side of Jordan and onwards, because we have our full inheritance on the side beyond Jordan eastward.
20 And Moses said to them, If ye will do according to these words, if ye will arm yourselves before the Lord for battle,
21 and every one of you will pass over Jordan fully armed before the Lord, until his enemy be destroyed from before his face,
22 and the land shall be subdued before the Lord, then afterwards ye shall return, and be guiltless before the Lord, and as regards Israel; and this land shall be to you for a possession before the Lord.
23 But if ye will not do so, ye will sin against the Lord; and ye shall know your sin, when afflictions shall come upon you.
