2 and it cometh to pass, on the third day, that lo, a man hath come in out of the camp from Saul, and his garments 'are' rent, and earth on his head; and it cometh to pass, in his coming in unto David, that he falleth to the earth, and doth obeisance.
Matthew Henry's Commentary on 2 Samuel 1:2
Commentary on 2 Samuel 1:1-10
(Read 2 Samuel 1:1-10)
The blow which opened David's way to the throne was given about the time he had been sorely distressed. Those who commit their concerns to the Lord, will quietly abide his will. It shows that he desired not Saul's death, and he was not impatient to come to the throne.
