Chapter 15 and 16 of Isaiah contain the prophet’s declaration of God’s judgment against the Moabites, enemies of the Israelites. The Lord would humiliate these people. Isaiah declared, by making them bald and cutting off their beards.
This was a sign of mourning among the Jewish people and other nations of the ancient world. When Ezra heard that some Israelite men had married pagan wives, he was so upset that he tore the hair off his head and face (Ezra 9:3). Job shaved his head to symbolized his misery and distress (Job 1:20).
ISAIAH 15:2 – He is gone up to Bajith, and to Dibon, the high places, to weep: Moab shall howl over Nebo, and over Medeba: on all their heads shall be baldness, and every beard cut off.
