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 you sent us has been translated and read in my presence.

19 I issued a decree and a search was conducted. It was discovered that this city has had uprisings against kings since ancient times, and there have been rebellions and revolts in it.

20 Powerful kings have also ruled over Jerusalem and exercised authority over the whole region, and tribute, duty, and land tax were paid to them.

21 Therefore, issue an order for these men to stop, so that this city will not be rebuilt until a [further] decree has been pronounced by me.

22 See that you not neglect this matter. Otherwise, the damage will increase and the royal interests will suffer.
