2 Chronicles 30:6 - Joseph Benson’s Commentary on the Old and New Testaments

So the posts Hebrew, הרצים, haratsim, the runners; went with the letters Expresses were sent throughout all the tribes of Israel, with memorials, earnestly pressing the people to take this opportunity of returning to God, from whom they had revolted. Saying, Ye children of Israel, turn again unto the Lord, &c. In these letters Hezekiah discovers great concern both for the honour of God and for the welfare of the neighbouring kingdom, the prosperity of which he seems earnestly to have desired, though he not only received no toll, tribute, or custom from it, but it had often, and not long since, been vexatious to his kingdom. This was indeed rendering good for evil. And he will return to the remnant of you You are but a remnant, narrowly escaped out of the hand of the kings of Assyria, (namely, Pul and Tiglath-pileser,) who have carried your brethren away captive. And therefore it concerns you to put yourselves under the protection of the God of your fathers, that you may not be quite swallowed up: and if you turn to him in the way of duty, he will turn to you in a way of mercy.
