Numbers 32:20-23

32:20 Then Moses replied, ¹  “If you will do this thing, and if you will arm yourselves for battle before the Lord, 32:21 and if all your armed men cross the Jordan before the Lord until he drives out his enemies from his presence 32:22 and the land is subdued before the Lord, then afterward you may return and be free of your obligation to the Lord and to Israel. This land will then be your possession in the Lord’s sight.

32:23 “But if you do not do this, then look, you will have sinned ²  against the Lord. And know that your sin will find you out.

[32:20]  ¹ tn Heb “said to them.”

[32:23]  ² tn The nuance of the perfect tense here has to be the future perfect.
