1 Kings 4:21; 1 Kings 4:24

21 Now Solomon ruled over all the kingdoms from the River to the land of the Philistines and to the border of Egypt; they brought tribute and served Solomon all the days of his life.

24 For he had dominion over everything west of the River, from Tiphsah even to Gaza, over all the kings west of the River; and he had peace on all sides around about him.
