(Ezekiel 16:7). When the children grew up, they came in flocks to their homes. When G-d revealed Himself in the Red Sea, these children recognized Him first, as it is said: “This is my G-d and I will praise Him” (Exodus 15:2).

(Midrash Tanchuma; Talmud, Sotah 11b)

The more they afflicted them, the more they multiplied and grew (genesis1 verse12)
