2 Samuel 19:40

Half the people of Israel. The northern tribes had been the first to debate the question of the king's recall ( 2 Samuel 19:9 ), while the men of Judah hung back. But at the instigation of the high priests and of Amasa, who was actually in command, they determined upon David's restoration, and acted so promptly and so independently of the rest of Israel that, when they reached Gilgal, only the delegates of a few tribes were in time to join them. As we read in 2 Samuel 19:41 of "all the men of Israel," it is evident that the rest had rapidly followed. It would have been well if the tribe of Judah had informed the rest of their purpose, as the bringing of David back would then have been the act of all Israel; but tribal jealousies were the cause of Israel's weakness throughout the time of the judges, and broke out into open disunion upon the death of Solomon.
