Sop

A morsel of bread (John 13:26; comp. Ruth 2:14). Our Lord took a piece of unleavened bread, and dipping it into the broth of bitter herbs at the Paschal meal, gave it to Judas. (Comp. Ruth 2:14.)

In eastern lands where our table utensils are unknown, the meat, with the broth, is brought upon the table in a large dish, and is eaten usually by means of pieces of bread clipped into the common dish. The bread so dipped is called. "It was such a piece of bread a sop dipped in broth that Jesus gave to Judas, (John 13:26) and again, in Matt 26:23 It is said "he that dippeth his hand with me in the dish," i.e. to make a sop by dipping a piece of bread into the central dish.

sop (psomion): A thin, wafer-like piece of bread dipped into the common dish as a sort of improvised spoon, is thus designated in Joh 13:26 ff.
