ashamed of his vision: In the Old Testament, people often called a prophet a visionary "seer" (see 1 Samuel 9:9–19; 2 Kings 17:13) because they received divine messages in dreams or night visions (for example, Zechariah 1:7–6:15).
hairy cloak: Old Testament Hebrew prophets wore a rough cloak made of camel or goat hair (see 2 Kings 1:8; Matthew 3:4).
