Psalm 18

The opening pile of titles is a soldier's vocabulary. "Rock" and "fortress" and "high tower" name the strongholds of the Judean wilderness, where a defensible crag with a spring could hold a small force against an army. A "horn" is the horn of a bull or a wild ox — raw, forward strength, the emblem used across the region for a king's power.

Verses 7–15 describe God's arrival in the language of a mountain storm: earth shaking, smoke, coals, thick darkness, hailstones, thunder, arrows of lightning, the channels of waters laid bare by his blast. Israel's neighbors told similar storm-language stories about Baal riding the clouds. This psalm uses the imagery and gives it to the Lord alone — and behind it lies a real event Israel never forgot, the descent on Sinai in fire and smoke.

"A bow of steel is broken by mine arms" refers to the composite bow, built up of wood, horn, and sinew and sometimes fitted with bronze. It was the high military technology of the age, expensive and hard to string; Egyptian and Assyrian reliefs show kings bending them as a display of strength.

"Thou hast enlarged my steps under me" is more concrete than it sounds. Fighting on the terraced, rocky slopes of Judah meant broken ground and turned ankles; a broad, level place under your feet was the difference between a stand and a rout. Verse 33 makes it explicit: feet like hinds' feet, sure on the high places, like the wild deer that cross a cliff face without slipping.
