"He chose the best land for himself; the leader's portion was kept for him. When the heads of the people assembled, he carried out the LORD's righteous will, and his judgments concerning Israel."
NIV
He selected the best land for himself, for there was the leader's portion reserved; yet he came with the chiefs of the nation, and the righteous will of the Lord he performed, and His ordinances with Israel. [Num. 32:29-33.]AMP
And he provided the first part for himself, because there, in a portion of the lawgiver, was he seated; and he came with the heads of the people, he executed the justice of the LORD, and his judgments with Israel.
