Deuteronomy 8:4

Thy raiment waxed not old. A miraculous intervention by God (see Deut. 29:5; Neh. 9:21). Apparently they were without means of providing sufficient clothing themselves; otherwise God would not have taken unusual steps to satisfy their requirements. God provided food, drink, protection, and other things when they could not help themselves.

Swell. The word thus translated appears elsewhere only in Neh. 9:21, and its meaning is rather obscure. It could perhaps mean “to blister.” The noun from the same root, however, is translated “dough” (Ex. 12:34, 39; Jer. 7:18; Hosea 7:4), no doubt because it swells as a result of the fermentation of yeast.
