John Gill's Bible Commentary Ver. 5. So Amasa went to assemble [the men of] Judah , etc.] To gather, them together out of their several tribes, and bring them to Jerusalem: but he tarried longer than the set time which he had appointed him : than the three days; whether this was owing to the remissness of Amasa, or the unwillingness of the people to serve under him, who had been Absalom’s general in the late rebellion, or not having time sufficient allowed him, is not certain.
Matthew Henry Commentary
Verses 4-13 - Joab barbarously murdered Amasa. The more plot there is in a sin, the worse it is. Joab contentedly sacrificed the interest both of the kin and the kingdom to his personal revenge. But one would wonder with what face a murderer could pursue a traitor; and how, under such a load of guilt, he had courage to enter upon danger: his conscience was seared.
