This refers to the conquest of Canaan and was written after that event.
11. “And while the children of Israel were in the wilderness they found a man that gathered sticks upon the Sabbath day” (Num. xv, 32).
When this was written the children of Israel were no longer in the wilderness. Their sojourn there is referred to as a past event. As Moses died while they were still in the wilderness—that is, before they had entered the promised land—it could not have been written by him.
12. “Thou shalt eat it within thy gates” (Deut. xv, 22).
The phrase, “within thy gates,” occurs in the Pentateuch about twenty-five times. It refers to the gates of the cities of the Israelites, which they did not inhabit until after the death of Moses.
13. “Ye shall therefore keep my statutes and my judgments, ... that the land spew not you out also, when ye defile it, as it spewed out the nations that were before you” (Lev. xviii, 26, 28).
When Moses died the nations alluded to still occupied the land and had not been expelled.
14. “And Abraham called the name of the place Jehovah-jireh: as it is said to this day, In the mount of the Lord it shall be seen” (Gen. xxii, 14).
This is one of the passages adduced by the critics of the seventeenth century against the Mosaic authorship of these books. It implies the conquest and a long occupancy of the land by the Israelites.
15. “And Sarah died in Kirjath-arba; the same is Hebron in the land of Canaan” (Gen. xxiii, 2). “And Jacob came ... unto the city of Arbah, which is Hebron” (xxxv, 27).
