'Covenant' in the Bible

Abner sent messengers to David {where he was}, saying, "To whom does the land [belong]? {Make your covenant with me}! Look, my hand [is] with you to bring all of Israel over to you!"

He said, "Good. {I will make a covenant with you}. I am asking only one thing from you: You shall not see my face unless you bring Michal the daughter of Saul when you come to see {me}."

And Abner said to David, "Let me get up and go and gather all of Israel to my lord the king, that they may {make a covenant} with you so you can reign over all which your soul desires." So David dismissed Abner, and he left in peace.

All the elders of Israel came to the king at Hebron, and King David {made a covenant} with them at Hebron in the presence of Yahweh; then they anointed David as king over Israel.

Suddenly Zadok [was] there, and all of the Levites with him, carrying the ark of the covenant of God. They set the ark of God down, and Abiathar offered sacrifices until all the people passed out of the city.

Yet not so [is] my house with God, for he made an everlasting covenant for me, arranging everything. He has secured all my deliverance, and all my desire he will cause to happen.
