Or HaChaim on Numbers 14:31/אור החיים על במדבר י״ד:ל״א

1 וטפכם אשר אמרתם לבז יהיה, "And as to your children of whom you said they will become prey, etc." Seeing that G'd had said He would do to the people in a manner corresponding to what they had said, and they had said that evil would befall their children if they listened to Caleb and Joshua, G'd now specifically exempts those children from the curse that they would not enter the Holy Land. The Torah adds the conjunctive letter ו in front of the word והבאתי אותם, "and I will bring them," to tell us that not only will these children not become prey, but they will inherit the land their parents should have inherited.
