Rabbi Nehorai said in a discourse: The daughters of Israel passed through the sea holding their children with their hand; and when these cried, they would stretch out their hands and pluck an apple or a pomegranate from the sea and give it to them, for it says, And He led them through the depths, as through a wilderness (PS.CVI, 9). Just as they lacked nothing in the wilderness, so also in the depths they lacked nothing. [footnote states: "This is his explanation of the difficulty: THEY WENT INTO THE MIDST OF THE SEA as though they were UPON THE DRY GROUND, finding everything there."]
This is what Moses said to them: These forty years the Lord thy God hath been with thee; and thou hast lacked nothing (Deut. II, 7). They were never in need of anything; they had only to mention a thing and it was immediately created for them. Rabbi Simeon said: They did not find it even necessary to utter a word; they had only to think of anything, and it was immediately fulfilled, as it says, And they tried God in their heart by asking food for their craving (Ps. LXXVIII, 18).
