Matthew Henry on 2 Samuel 16:15–end
Absalom had notice sent him speedily by some of his friends at Jerusalem that David had withdrawn, and with what a small retinue he had gone; so that the coasts were clear, Absalom might take possession of Jerusalem when he pleased. The gates were open, and there was none to oppose him. Accordingly he came without delay (Sa2 16:15), extremely elevated, no doubt, with this success at first, and that that in which, when he formed his design, he probably apprehended the greatest difficulty, was so easily and effectually done.

John Gill on 2 Samuel 16:18
And Hushai said to Absalom,.... In answer to his questions:
