Mighty kings ... - If this reference can scarcely have been to David or Solomon (see marginal reference), of whom neither the Babylonian nor the Assyrian archives would be likely to have had any account - it would probably be to Menahem 2 Kings 15:16 and Josiah (2 Chronicles 34:6-7; 2 Chronicles 35:18).

Beyond the river - That is, the Euphrates. Both David and Solomon carried their conquests beyond this river. See 2 Samuel 8:3, etc., and 1 Kings 4:21, where it is said, Solomon reigned over all kingdoms from the river (Euphrates) unto the land of the Philistines; and unto the borders of Egypt.

There have been mighty kings also over Jerusalem, which have ruled over all countries beyond the river,.... As David and Solomon; and the account of these they had in their records, see 2 Samuel 8:1

and toll, tribute, and custom, was paid unto them; as appears from the places referred to; and this served to strengthen the insinuation made to the king, that if these people were suffered to go on building, he would lose his tribute and taxes in those parts.

"There have been powerful kings in Jerusalem, and (rulers) exercising dominion over the whole region beyond the river" (westward of Euphrates). This applies in its full extent only to David and Solomon, and in a less degree to subsequent kings of Israel and Judah. On Ezra 4:20, comp. Ezra 4:13.

There have been mighty kings also over Jerusalem, which have ruled over all countries beyond the river; and toll, tribute, and custom, was paid unto them.

4:6-24 It is an old slander, that the prosperity of the church would be hurtful to kings and princes. Nothing can be more false, for true godliness teaches us to honour and obey our sovereign. But where the command of God requires one thing and the law of the land another, we must obey God rather than man, and patiently submit to the consequences. All who love the gospel should avoid all appearance of evil, lest they should encourage the adversaries of the church. The world is ever ready to believe any accusation against the people of God, and refuses to listen to them. The king suffered himself to be imposed upon by these frauds and falsehoods. Princes see and hear with other men's eyes and ears, and judge things as represented to them, which are often done falsely. But God's judgment is just; he sees things as they are.
