1 Chronicles 11:1-3

Then all Israel gathered to David at Hebron, saying, “Behold, we are your bone and your flesh. [2 Sam 2:8-10] In times past, even when Saul was king, it was you who led out and brought in Israel; and the LORD your God said to you, ‘You shall shepherd My people Israel, and you shall be prince and leader over My people Israel.’ ” So all the elders of Israel came to the king at Hebron, and David made a covenant (solemn agreement) with them there before the LORD; and they anointed him king over Israel, in accordance with the word of the LORD through Samuel. [1 Sam 16:1, 12, 13]
