Genesis 37:23-25

Now when Joseph reached his brothers, they stripped him of his tunic, the [distinctive] multicolored tunic which he was wearing; then they took him and threw him into the pit. Now the pit was empty; there was no water in it. Then they sat down to eat their meal. When they looked up, they saw a caravan of Ishmaelites coming from Gilead [east of the Jordan], with their camels bearing ladanum resin [for perfume] and balm and myrrh, going on their way to carry the cargo down to Egypt.
