English: R’ Yishmael says: Scripture changed this “coming” from all other “comings” in the Torah… here it says “when you come” — to teach you that as soon as they entered the land they were immediately obligated in challah.
Type of Learning
Immediate obligation without waiting for conquest and division.
What Is Learned
Unlike other land-dependent mitzvos, challah attaches from the first entry and first bread of the land.
