'Covenant' in the Bible

Then Abner sent messengers to David in his place, saying, “Whose is the land? Make your covenant with me, and behold, my hand shall be with you to bring all Israel over to you.”

He said, “Good! I will make a covenant with you, but I demand one thing of you, namely, you shall not see my face unless you first bring Michal, Saul’s daughter, when you come to see me.”

Abner said to David, “Let me arise and go and gather all Israel to my lord the king, that they may make a covenant with you, and that you may be king over all that your soul desires.” So David sent Abner away, and he went in peace.

So all the elders of Israel came to the king at Hebron, and King David made a covenant with them before the Lord at Hebron; then they anointed David king over Israel.

So the king called the Gibeonites and spoke to them (now the Gibeonites were not of the sons of Israel but of the remnant of the Amorites, and the sons of Israel made a covenant with them, but Saul had sought to kill them in his zeal for the sons of Israel and Judah).

“Truly is not my house so with God?For He has made an everlasting covenant with me,Ordered in all things, and secured;For all my salvation and all my desire,Will He not indeed make it grow?
