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.

Numbers 32:19 Meaning and Commentary

Numbers 32:19

For we will not inherit with them on yonder side Jordan, or
forward
This they said, not as being determined whether Moses and the princes were willing or not to stay where they were, and not pass over Jordan to inherit any part there, and much less as despising the good land, but as giving up all pretensions to it, should they be settled where they desired; they were not of that selfish and covetous disposition as to desire any part on the other side Jordan, if it was but granted them to continue on this side, and possess the land they requested:

because our inheritance is fallen to us on this side Jordan eastward;
they seem to speak as if they were assured of it, and that it was so ordered by divine Providence, and wanted nothing but the consent of Moses, and the princes of the congregation.

Numbers 32:19 In-Context

17 and we will arm ourselves and go as an advanced guard before the children of Israel, until we shall have brought them into their place; and our possessions shall remain in walled cities because of the inhabitants of the land.
18 We will not return to our houses till the children of Israel shall have been distributed, each to his own inheritance.
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,
