The children of Israel, after Joseph's death, do multiply.
Exodus 1:1 Now these [are] the names of the children of Israel, which came into Egypt; every man and his household came with Jacob. Exodus 1:2 Reuben, Simeon, Levi, and Judah, Exodus 1:3 Issachar, Zebulun, and Benjamin, Exodus 1:4 Dan, and Naphtali, Gad, and Asher. Exodus 1:5 And all the souls that came out of the loins of Jacob were seventy souls: for Joseph was in Egypt [already]. Exodus 1:6 And Joseph died, and all his brethren, and all that generation.
Exodus 1:7 And the children of Israel were fruitful, and increased abundantly, and multiplied, and waxed exceeding mighty; and the land was filled with them.
The more they are oppressed by a new king, the more they multiply.
Exodus 1:8 Now there arose up a new king over Egypt, which knew not Joseph. Exodus 1:9 And he said unto his people, Behold, the people of the children of Israel [are] more and mightier than we: Exodus 1:10 Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and [so] get them up out of the land. Exodus 1:11 Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh treasure cities, Pithom and Raamses. Exodus 1:12 But the more they afflicted them, the more they multiplied and grew. And they were grieved because of the children of Israel. Exodus 1:13 And the Egyptians made the children of Israel to serve with rigour: Exodus 1:14 And they made their lives bitter with hard bondage, in morter, and in brick, and in all manner of service in the field: all their service, wherein they made them serve, [was] with rigour.
The godliness of the midwives, in saving the men children alive.
Exodus 1:15 And the king of Egypt spake to the Hebrew midwives, of which the name of the one [was] Shiphrah, and the name of the other Puah: Exodus 1:16 And he said, When ye do the office of a midwife to the Hebrew women, and see [them] upon the stools; if it [be] a son, then ye shall kill him: but if it [be] a daughter, then she shall live. Exodus 1:17 But the midwives feared God, and did not as the king of Egypt commanded them, but saved the men children alive. Exodus 1:18 And the king of Egypt called for the midwives, and said unto them, Why have ye done this thing, and have saved the men children alive? Exodus 1:19 And the midwives said unto Pharaoh, Because the Hebrew women [are] not as the Egyptian women; for they [are] lively, and are delivered ere the midwives come in unto them. Exodus 1:20 Therefore God dealt well with the midwives: and the people multiplied, and waxed very mighty. Exodus 1:21 And it came to pass, because the midwives feared God, that he made them houses.
Pharaoh commandeth the male children to be cast into the river.
Exodus 1:22 And Pharaoh charged all his people, saying, Every son that is born ye shall cast into the river, and every daughter ye shall save alive.
