Joshua 16:4 - Matthew Poole's English Annotations on the Holy Bible

Manasseh, i.e. half Manasseh, by a synecdoche. Their inheritance, i.e. their several portions which here follow. Some think that they had but one lot between them; and therefore they are now said to take their inheritance, to wit, by dividing it between them according to the direction of Joshua and Eleazar, &c.; for that phrase being used of them, and not to my remembrance of any other tribes, may seem to have some peculiar signification, which doth not agree to the other tribes. But there being mention of a peculiar lot taken out for Manasseh, Joshua 17:1, shows that their several inheritances fell to them, as the rest did to the other tribes, even by several lots; and it is said of them, that they took their inheritance, which also Judah had done before them, because the tribes of Judah and Joseph did take their inheritances before the rest; and it was fit they should do so, for the security of the main camp, and the body of the people which were at Gilgal. See Joshua 18:5.
