Genesis 37:23-25

23And it came to pass when Joseph came to his brethren, that they stripped Joseph of his vest, the vest of many colours, which he had on;

24and they took him and cast him into the pit; now the pit was empty — there was no water in it.

25And they sat down to eat bread; and they lifted up their eyes and looked, and behold, a caravan of Ishmaelites came from Gilead; and their camels bore tragacanth, and balsam, and ladanum — going to carry [it] down to Egypt.
