1 Kings 4:21

And Solomon reigned over all kingdoms,.... Not only over Judah and Israel, but all people round about him, they standing in fear of him; or who brought him presents, or paid tribute to him, which was an acknowledgment of superiority over them, and doing homage to him:

from the river unto the land of the Philistines, and unto the border of Egypt; that is, from the river Euphrates, as the Targum, which was the border of his proper domains to the east, to Palestine, inhabited by the Philistines, which lay to the west, and as far as the border of Egypt, which was the southern boundary; a like and larger extent of Christ's kingdom is given, Psalms 72:8;

and they brought presents, and served Solomon all the days of his life; this explains in what sense other kingdoms besides were ruled by Solomon, and subject to him; of Christ his antitype, see Psalms 72:10.
