David
Psalm 18:12ESV·traditional attribution

Out of the brightness before him hailstones and coals of fire broke through his clouds.

John Calvin Reformed @genevareformer

PSALM 18. We all know through what difficulties and almost insurmountable obstacles David came to the kingdom. Even to the time of Saul’s death he was a fugitive, and, as it were, an outlaw, and wearily passed his life in fear, amidst many threatenings and dangers of death.

In most poetical language the Psalmist now describes his experience of Jehovah's delivering power. Poesy has in all her treasures no gem more lustrous than the sonnet of the following verses; the sorrow, the cry, the descent of the Divine One, and the rescue of the afflicted, are here set to a music worthy of the golden harps.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Suddenly the terrible artillery of heaven was discharged; the brightness of lightning lit up the clouds as with a glory proceeding from him who was concealed within the cloudy pavilion; and volleys of hailstones and coals of fire were hurled forth upon the enemy.
