3. shepherds--the Jewish rulers.

their glory--their wealth and magnificence; or that of the temple, "their glory" (Mr 13:1; Lu 21:5).

young lions--the princes, so described on account of their cruel rapacity.

The valley of the Jordan forms a deeper gash than any on the earth. The land at Lake Merom is on a level with the Mediterranean Sea; at the Sea of Tiberias it falls six hundred fifty feet below that level, and to double that depression at the Dead Sea, that is, in all, 1950 feet below the Mediterranean; in twenty miles' interval there is a fall of from three thousand to four thousand feet.
