'Agreement' in the Bible
Then Abner sent messengers to David saying, "To whom does the land belong? Make an agreement with me, and I will do whatever I can to cause all Israel to turn to you."
So David said, "Good! I will make an agreement with you. I ask only one thing from you. You will not see my face unless you bring Saul's daughter Michal when you come to visit me."
Abner said to David, "Let me leave so that I may go and gather all Israel to my lord the king so that they may make an agreement with you. Then you will rule over all that you desire." So David sent Abner away, and he left in peace.
When all the leaders of Israel came to the king at Hebron, King David made an agreement with them in Hebron before the Lord. They designated David as king over Israel.
