Any children born to you after them will be yours; in the territory they inherit they will be reckoned under the names of their brothers.
NIV
But other sons who may be born after them shall be your own; and they shall be called after the names of these [two] brothers and reckoned as belonging to them [when they come] into their inheritance.
AMP
And thy issue, which thou begettest after them, shall be thine, and shall be called after the name of their brethren in their inheritance.
KJV
"We will not receive any inheritance with them on the other side of the Jordan, because our inheritance has come to us on the east side of the Jordan."
NIV
For we will not inherit with them on the [west] side of the Jordan and beyond, because our inheritance is fallen to us on this side of the Jordan eastward.
AMP
For we will not inherit with them on yonder side Jordan, or forward; because our inheritance is fallen to us on this side Jordan eastward.
KJV
