Abrahamic Covenant
When defining the land promised to Abram and his offspring, the Lord said, “To your offspring I give this land, from the river of Egypt to the great river, the river Euphrates, the land of the Kenites, the Kenizzites, the Kadmonites, the Hittites, the Perizzites, the Rephaim, the Amorites, the Canaanites, the Girgashites and the Jebusites.” (Genesis 15:18-21)

Samuel told Saul the LORD wanted him to destroy Amalek and all their livestock for how they treated Israel when they came out of Egypt. He summoned his forces to Telaim and, after warning the Kenites to flee after their kindness shown to Israel as they came out of Egypt, Saul and two hundred thousand foot soldiers and ten thousand men of Judah defeated the Amalekites from Havilah as far as Shur. (1 Samuel 15)
After fleeing from Saul to Philistia with Achish the son of Maoch, king of Gath, David made Ziklag his base of operations for military exploits against the Geshurites, Girzites, and Amalekites as far as Shur, to the land of Egypt. He reported his raids back to Achish as against the Negeb of Judah, Jerahmeelites, and Kenites and gained Achish's trust. (1 Samuel 27)

When he returned to Ziklag, he sent part of the spoil to his friends, the elders of Judah, saying, "Here is a present for you from the spoil of the enemies of the LORD." It was for those in Bethel, Ramoth of the Negeb, Jattir, Aroer, Siphmoth, Eshtemoa, Racal, the cities of the Jerahmeelites and Kenites, in Hormah, Borashan, Athach, Hebron, for all the places where David and his men had roamed.
