And numerous, as thus growth of the field: Just as the growth of the field, when they are cut down grow back even more numerous, so too, Israel the more they were oppressed the more they increased ant became fertile.

But you were naked and bare: Naked and lacking in commandments so that when the end of the subjugation came, they did not have any commandments to their credit. Therefore God gave them the Passover offering and the commandment to circumcise all the males on the fourteenth day of Nisan. This is hinted at in the verse: "When I passed by you and saw you wallowing in blood, I said to you: "live in spite of your blood; yea, live in spite of your blood" (Ezekiel 16:7). The verse refers to the blood of circumcision and the blood of the offering.
