Charles H. Spurgeon on Psalms 144:5

Touch the mountains, and they shall smoke. The meaning is, when God doth but lay his hand upon great men, upon the mightiest of the world, he makes them smoke or fume, which some understand of their anger; they are presently in a passion, if God do but touch them. Or we may understand it of their consumption. A smoking mountain will soon be a burnt mountain. In our language, to make a man smoke is a proverbial expression for destroying or subduing. —Joseph Caryl.

Verses 5-6.

Bow thy heavens, Jehovah,

Come down in thy might;

Let the rays of thy glory

The mountaintops light.

With the bolts of thy thunder

Discomfit my foe,

With the flash of thine arrows

Their force overthrow. —William Digby Seymour.
