Ezra 4:17

Then sent the king an answer unto Rehum the chancellor, and to
Shimshai the scribe
This affair, upon examination, being found to be of importance, the king of Persia thought fit to send an answer to the above letter, which was doing them an honour, and gave them the power and authority they wished to have:

and to the rest of their companions that dwelt in Samaria;
in the kingdom, province, and cities of Samaria:

and unto the rest beyond the river;
the river Euphrates, the rest of the nations before mentioned, ( Ezra 4:9 Ezra 4:10 ) .

Peace, and at such a time:
that is, all health and prosperity
