Numbers 15:18

Speak unto the children of Israel, and say unto them,.... Who only were bound to observe the following law concerning the cake of the first dough, Numbers 15:20, and not Gentiles; so the Jews say k, the dough of a Gentile is free from the cake, though an Israelite kneads it:

when ye come into the land whither I bring you; the land of Canaan: this is another assurance of their possession of the land of Canaan, notwithstanding what had been threatened; in Numbers 15:2; it is only said, "which I give unto you", but here, "whither I bring you"; assuring them, that as he had given it unto them, he would certainly introduce them into it. The Jews from hence gather, that they are not bound to observe this precept concerning the cake by the law, but in the land of Israel only, and when all Israel are there; wherefore at this time, and even in the days of Ezra, it is separated only by the words of the Scribes; and the reason of it is, that this law might not be forgotten by the Israelites l: there were three countries that were bound to bring the cake, according to the Misnah m.
