Genesis 37:23-25

When Joseph reached his brothers, they stripped him of his tunic, the special tunic that he wore. Then they took him and threw him into the cistern. (Now the cistern was empty; there was no water in it.) When they sat down to eat their food, they looked up and saw a caravan of Ishmaelites coming from Gilead. Their camels were carrying spices, balm, and myrrh down to Egypt.
