Barnes' Notes
He tarried - The cause of Amasa' s delay is not stated. It may have been the unwillingness of the men of Judah to place themselves under his orders, or it may have been caused by a wavering or hesitation in loyalty. This last is evidently insinuated in II Samuel 20:11, and no doubt this was the pretext, whether grounded in fact or not, by which Joab justified the murder of Amasa before David.
