'Agreement' in the Bible

And you will be certain that I have sent this order to you, so that it might be my agreement with Levi, says the Lord of armies.

My agreement with him was on my side life and peace, and I gave them to him; on his side fear, and he had fear of me and gave honour to my name.

But you are turned out of the way; you have made the law hard for numbers of people; you have made the agreement of Levi of no value, says the Lord of armies.

Have we not all one father? has not one God made us? why are we, every one of us, acting falsely to his brother, putting shame on the agreement of our fathers?

See, I am sending my servant, and he will make ready the way before me; and the Lord, whom you are looking for, will suddenly come to his Temple; and the angel of the agreement, in whom you have delight, see, he is coming, says the Lord of armies.
