(2.) These intestine broils should be not only among particular persons and private families, but among the tribes (v. 21): Manasseh shall devour Ephraim, and Ephraim Manasseh, though they be combined against Judah. Those that could unite against Judah could not unite with one another; but that sinful confederacy of theirs against their neighbour that dwelt securely by them was justly punished by this separation of them one from another. Or Judah, having sinned like Manasseh and Ephraim, shall not only suffer with them, but suffer by them. Note, Mutual enmity and animosity among the tribes of God's Israel is a sin that ripens them for ruin, and a sad symptom of ruin hastening on apace. If Ephraim be against Manasseh, and Manasseh against Ephraim, and both against Judah, they will all soon become a very easy prey to the common enemy.
