20 There have also been mighty kings over Jerusalem, who have ruled over all the region beyond the River; and tax, tribute, and custom were paid to them.

Ezra 4:20 Meaning and Commentary

Ezra 4:20

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 ) ( 1 Kings 4:21 1 Kings 4:24 )

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.

Ezra 4:20 In-Context

18 The letter which you sent to us has been clearly read before me.

19 And I gave the command, and a search has been made, and it was found that this city in former times has revolted against kings, and rebellion and sedition have been fostered in it.

20 There have also been mighty kings over Jerusalem, who have ruled over all the region beyond the River; and tax, tribute, and custom were paid to them.

21 Now give the command to make these men cease, that this city may not be built until the command is given by me.

22 Take heed now that you do not fail to do this. Why should damage increase to the hurt of the kings?
