'Behalf' in the Bible

"Now you, Ezra, in keeping with the wisdom of your God which you possess, appoint judges and court officials who can arbitrate cases on behalf of all the people who are in Trans-Euphrates who know the laws of your God. Those who do not know this law should be taught.

Let our leaders take steps on behalf of all the assembly. Let all those in our towns who have married foreign women come at an appointed time, and with them the elders of each town and its judges, until the hot anger of our God is turned away from us in this matter."
