Genesis 37:23-28

So it came about, when Joseph reached his brothers, that they stripped Joseph of his tunic, the varicolored tunic that was on him; and they took him and threw him into the pit. Now the pit was empty, without any water in it. Then they sat down to eat a meal. And as they raised their eyes and looked, behold, a caravan of Ishmaelites was coming from Gilead, with their camels bearing aromatic gum and balm and myrrh, on their way to bring them down to Egypt. Judah said to his brothers, “What profit is it for us to kill our brother and cover up his blood? Come and let us sell him to the Ishmaelites and not lay our hands on him, for he is our brother, our own flesh.” And his brothers listened to him. Then some Midianite traders passed by, so they pulled him up and lifted Joseph out of the pit, and sold him to the Ishmaelites for twenty shekels of silver. Thus they brought Joseph into Egypt.
