מדרש על ירמיהו 11:4

Rabbi 'Aḳiba said: The executioners of Pharaoh used to strangle the Israelites in the walls of the houses, || and the Holy One, blessed be He, heard their cry, as it is said, "And God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob" (Ex. 2:24). Further, they burnt their children in the furnace of fire, as it is said, "But the Lord hath taken you, and brought you forth out of the iron furnace, out of Egypt" (Deut. 4:20).
