2 Samuel 2:3-7

And David brought up his men who were with him, each with his household; and they settled in the cities of Hebron.

Then the men of Judah came, and there they anointed David king over the house of Judah. And they told David, saying, “It was the men of Jabesh-gilead who buried Saul.”

So David sent messengers to the men of Jabesh-gilead, and said to them, “May you be blessed of the Lord because you have shown this kindness to Saul your lord, and have buried him.

And now may the Lord show kindness and truth to you; and I also will show this goodness to you, because you have done this thing.

Now then, let your hands be strong and be valiant, since Saul your lord is dead, and also the house of Judah has anointed me king over them.” Ish-bosheth Made King over Israel
