Numbers 32:19

19 We will not inherit with them on the other side of the Jordan and beyond, because our inheritance has come to us on this side of the Jordan to the east."

Numbers 32:19 In-Context

17 but we will take up arms as a vanguard before the Israelites, until we have brought them to their place. Meanwhile our little ones will stay in the fortified towns because of the inhabitants of the land.
18 We will not return to our homes until all the Israelites have obtained their inheritance.
19 We will not inherit with them on the other side of the Jordan and beyond, because our inheritance has come to us on this side of the Jordan to the east."
20 So Moses said to them, "If you do this—if you take up arms to go before the Lord for the war,
21 and all those of you who bear arms cross the Jordan before the Lord, until he has driven out his enemies from before him
