'Law' in the Bible

And Terah took Abram, his son, and Lot, the son of Haran, and Sarai, his daughter-in-law, the wife of his son Abram and they went out from Ur of the Chaldees, to go to the land of Canaan; and they came to Haran, and were there for some time.

Then the men said to Lot, Are there any others of your family here? sons-in-law or sons or daughters, take them all out of this place;

And Lot went out and said to his sons-in-law, who were married to his daughters, Come, let us go out of this place, for the Lord is about to send destruction on the town. But his sons-in-law did not take him seriously.

Then Judah said to Tamar, his daughter-in-law, Go back to your father's house and keep yourself as a widow till my son Shelah becomes a man: for he had in his mind the thought that death might come to him as it had come to his brothers. So Tamar went back to her father's house.

And when Tamar had news that her father-in-law was going up to Timnah to the wool-cutting,

And turning to her by the roadside, he said to her, Let me come in to you; for he had no idea that she was his daughter-in-law. And she said, What will you give me as my price?

Now about three months after this, word came to Judah that Tamar, his daughter-in-law, had been acting like a loose woman and was with child. And Judah said, Take her out and let her be burned.

And while she was being taken out, she sent word to her father-in-law, saying, The man whose property these things are, is the father of my child: say then, whose are this ring and this cord and this stick?

Then Joseph made a law which is in force to this day, that Pharaoh was to have the fifth part; only the land of the priests did not become his.
