11 Then King David sent Zadok and Abiathar, the priests, to say to the elders of Judah, "Why are you the last ones to welcome back the king into his palace? For I have heard that all Israel is ready.

Matthew Henry's Commentary on 2 Samuel 19:11

Commentary on 2 Samuel 19:9-15

(Read 2 Samuel 19:9-15)

God's providence, by the priests' persuasions and Amasa's interest, brought the people to resolve the recall of the king. David stirred not till he received this invitation. Our Lord Jesus will rule in those that invite him to the throne in their hearts, and not till he is invited. He first bows the heart, and makes it willing in the day of his power, then rules in the midst of his enemies, Psalm 110:2,3.
