Grapesyrup or "dibs." The Arabs take the juice of grapes, and boil it until it is as thick as molasses. They call this "dibs," and they are very fond of eating it with bread, or they thin it with water and drink it. This grapehoney was in use in Bible times. It was probably this that Jacob sent to Joseph in Egypt (Genesis 43:11), and which was purchased by the Tyrians from the land of Israel (Ezekiel 27:17). Three hundred pounds of grapes will make one hundred pounds of dibs. [Manners And Customs of Bible Lands]
