Genesis 37:25-28

25And as they sat down to eat a meal, they looked up and saw a caravan of Ishmaelites coming from Gilead. Their camels were carrying spices, balm, and myrrh on their way down to Egypt.

26Then Judah said to his brothers, “What profit will we gain if we kill our brother and cover up his blood? 27Come, let us sell him to the Ishmaelites and not lay a hand on him; for he is our brother, our own flesh.” And they agreed. 28So when the Midianite traders passed by, his brothers pulled Joseph out of the pit and sold him for twenty shekels of silver1 to the Ishmaelites, who took him to Egypt.
