Genesis 37:25; Genesis 37:28; Genesis 37:36

25 As they sat down to eat their meal, they looked up and saw a caravan of Ishmaelites coming from Gilead. Their camels were loaded with spices, balm and myrrh, and they were on their way to take them down to Egypt.

28 So when the Midianite merchants came by, his brothers pulled Joseph up out of the cistern and sold him for twenty shekels of silver to the Ishmaelites, who took him to Egypt.

36 Meanwhile, the Midianites sold Joseph in Egypt to Potiphar, one of Pharaoh’s officials, the captain of the guard.
