'Requires' in the Bible

"Receive these gifts from them, that they may be used in doing the work of the tent of meeting; and you must give them to the Levites, to every man as his service requires."

You must love the Lord your God and do what he requires; keep his statutes, ordinances, and commandments at all times.

I thought, "Surely it is only the ignorant poor who act this way. They act like fools because they do not know what the Lord demands. They do not know what their God requires of them.

I will go to the leaders and speak with them. Surely they know what the Lord demands. Surely they know what their God requires of them." Yet all of them, too, have rejected his authority and refuse to submit to him.
