'Let There Be' in the Bible

“Let there be a treaty between you and me, as there was between my father and your father. Look, I am sending you silver and gold; go, break your treaty with Baasha king of Israel, so that he will withdraw from me.”

And stand in the holy place according to the divisions of the fathers houses of your brethren the children of the people, and let there be for each a portion of a fathers house of the Levites.
