Moses
Deuteronomy 29:8ESV·traditional attribution

We took their land and gave it for an inheritance to the Reubenites, the Gadites, and the half-tribe of the Manassites.

Matthew Henry Presbyterian @wholebiblehenry

Now that Moses had largely repeated the commands which the people were to observe as their part of the covenant, and the promises and threatenings which God would make good (according as they behaved themselves) as part of the covenant, the whole is here summed up in a federal transaction.

And we took their land,.... Which belonged to the two kings, the lands of Jazer, Gilead, and Bashan, fine countries for pasturage: and gave it for an inheritances unto the Reubenites, and to the Gadites, and to the half tribe of Manasseh; who requested it, and to whom it was granted on certain conditions, and they were now in possession of it; see Num 32:1.

Deu 29:5-8 With the appeal to the gracious guidance of Israel by God through the desert, the address of Moses passes imperceptibly into an address from the Lord, just as in Deu 11:14. (On Deu 29:5, Deu 29:6, vid., Deu 8:3-4; on Deu 29:7, vid., Deu 2:26., and Deu 3:1. and Deu 3:12.).
