Genesis 37:24,25

They cast him into a pit To perish there with hunger and cold; so cruel were their tender mercies. They sat down to eat bread They felt no remorse of conscience, which, if they had, would have spoiled their stomachs to their meat. A great force put upon conscience commonly stupifies it, and for the time deprives it both of sense and speech. A company of Ishmaelites In Genesis 37:28; Genesis 37:36, they are termed also Midianites, or, as it is in the Hebrew of Genesis 37:36, Medanites. It seems these different tribes, which were descended from the sons of Abraham, Medan, and Midian, by Keturah, and of Ishmael, by Hagar, were joined in one caravan, or company of merchants, bringing spicery, balm, and myrrh upon their camels from Gilead, a place noted for these articles, and carrying them into Egypt.
