4:24 For he had dominion over all [the region] on this side the river, from Tiphsah even to Azzah, over all the {h} kings on this side the river: and he had peace on all sides round about him.
(h) For they were all tributaries to him.
4:24 Tiphsah - Either that Tiphsah, 2Kings 15:16, which was in the kingdom of Israel within Jordan; or, rather, another place of that name upon Euphrates, even that eminent city which is mentioned by Ptolemy, and Strabo, and Pliny, called Thapsarum. And this best agrees with the following: Azzah, which was the border of Canaan in the south and west, as Tiphsah was in the north and east. And so his dominion is described by both its borders. All kings - Who owned subjection, and paid tribute to him.
4:20-28 Never did the crown of Israel shine so bright, as when Solomon wore it. He had peace on all sides. Herein, his kingdom was a type of the Messiah's; for to Him it is promised that he shall have the heathen for his inheritance, and that princes shall worship him. The spiritual peace, and joy, and holy security, of all the faithful subjects of the Lord Jesus, were typified by that of Israel. The kingdom of God is not, as Solomon's was, meat and drink, but, what is infinitely better, righteousness, and peace, and joy in the Holy Ghost. The vast number of his attendants, and the great resort to him, are shown by the provision daily made. Herein Christ far outdoes Solomon, that he feeds all his subjects, not with the bread that perishes, but with that which endures to eternal life.
