1Now these are the names of the sons of Israel, who came into Egypt (every man and his household came with Jacob): 2Reuben, Simeon, Levi, and Judah, 3Issachar, Zebulun, and Benjamin, 4Dan and Naphtali, Gad and Asher. 5All the souls who came out of Jacob’s body were seventy souls, and Joseph was in Egypt already. 6Joseph died, as did all his brothers, and all that generation. 7The children of Israel were fruitful, and increased abundantly, and multiplied, and grew exceedingly mighty; and the land was filled with them.
8Now there arose a new king over Egypt, who didn’t know Joseph. 9He said to his people, “Behold, the people of the children of Israel are more and mightier than we. 10Come, let’s deal wisely with them, lest they multiply, and it happen that when any war breaks out, they also join themselves to our enemies and fight against us, and escape out of the land.” 11Therefore they set taskmasters over them to afflict them with their burdens. They built storage cities for Pharaoh: Pithom and Raamses. 12But the more they afflicted them, the more they multiplied and the more they spread out. They started to dread the children of Israel. 13The Egyptians ruthlessly made the children of Israel serve, 14and they made their lives bitter with hard service in mortar and in brick, and in all kinds of service in the field, all their service, in which they ruthlessly made them serve.
15The king of Egypt spoke to the Hebrew midwives, of whom the name of the one was Shiphrah, and the name of the other Puah, 16and he said, “When you perform the duty of a midwife to the Hebrew women, and see them on the birth stool, if it is a son, then you shall kill him; but if it is a daughter, then she shall live.” 17But the midwives feared God, and didn’t do what the king of Egypt commanded them, but saved the baby boys alive. 18The king of Egypt called for the midwives, and said to them, “Why have you done this thing and saved the boys alive?”
19The midwives said to Pharaoh, “Because the Hebrew women aren’t like the Egyptian women; for they are vigorous and give birth before the midwife comes to them.”
20God dealt well with the midwives, and the people multiplied, and grew very mighty. 21Because the midwives feared God, he gave them families. 22Pharaoh commanded all his people, saying, “You shall cast every son who is born into the river, and every daughter you shall save alive.”
Judah was the fourth son of Jacob and Leah, and one of the twelve sons of Jacob, his name in Hebrew is Yehudah, meaning praise. Jacob is one of the more significant figures in the Bible. The important tribe of Judah is named after the patriarch Judah, since King David, and ultimately Jesus the Messiah, came from this tribe.
In the well-known study relating to the selling of Joseph into slavery because of the anger of the brothers against Joseph and their decision to kill him. Judah intercedes and convinces them to sell Joseph to some traders who were passing through, which enabled him to become a leader in Egypt.
In addition to this event regarding Joseph, Judah is also known because of his involvement regarding Tamar. According to custom, when a man died, the woman was to be married to a brother of the brother who died (later known as the levirate law). After two of Judah's sons died, it was custom for Judah to marry then the third son and bear a child for the deceased son. Tamar attempted to avoid this custom and dressed as a prostitute and tricked Judah to have sex with her, which resulted in her giving birth to two sons, Perez and Zerah, which then continued the line of Judah, from which the Messiah came.
