Genesis 37:23-25

So when Joseph came to his brothers, they stripped him of his robe, the robe of many colors that he wore. And they took him and threw him into a pit. The pit was empty; there was no water in it. Then they sat down to eat. And looking up they saw a caravan of Ishmaelites coming from Gilead, with their camels bearing gum, balm, and myrrh, on their way to carry it down to Egypt.
