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 entire letter that you sent to us has been read in translation for me.

19 I issued an order; they searched and discovered that this city has revolted against kings over a long period of time. There has been much rebellion and revolt there.

20 However, there have been mighty kings over Jerusalem who also ruled over the whole province Beyond the River. Tribute and taxes and dues were paid to them.

21 Therefore, issue an order to stop these people: this city is not to be rebuilt until I make a decree.

22 Be sure to carry out this order! Why should danger grow and threaten the king?
