ישעיהו סג:יג פירוש: רש״י ואבן עזרא

like a horse in the desert which does not stumble since it is smooth land, so they did not stumble in the deep.

The deep. The sea.

In the wilderness, which is upon dry land.²¹I. E. divides the verse into two sentences, He led them through the deep, and He led them, (to be supplied) in the wilderness, or, in the plain, while, according to others, the verse contains only one sentence, He led them through the deep, as a horse (is safely led) in the wilderness.
