Zechariah uses the image of a winged sun disk, which artists showed as hovering protectively over the Persian king. The Lord will protect Israel, lead them in battle, and demonstrate his power.
The ram’s horn calls people together (Numbers 10:2–3, 7–10; Isaiah 27:13) and announces God’s presence and power (Exodus 19:19; 20:18).
The whirlwind shows God as a warrior with great power and quickness (Psalm 77:18; Isaiah 21:1; 29:6; 66:15). References to lightning remind us of Mount Sinai (Exodus 19:16) and God’s covenant promises to Israel.
