David
Psalm 37:15ESV·traditional attribution

their sword shall enter their own heart, and their bows shall be broken.

John Calvin Reformed @genevareformer

PSALM 37 This psalm, the title of which shows it to have been composed by David, contains most profitable instruction. Since the faithful, so long as they pursue their earthly pilgrimage through life, see things strangely confused in the world, unless they assuaged their grief with the hope of a better issue, their courage would soon fail them.

Here is the portrait of a proud oppressor armed to the teeth.

Commenting on Psalm 37:12

C.H. Spurgeon Reformed Baptist @princeofpreachers

Their sword shall enter into their own heart. Like Haman they shall be hanged upon the gallows built by themselves for Mordecai. Hundreds of times has this been the case. Saul, who sought to slay David, fell on his own sword; and the bow, his favourite weapon, the use of which he taught the children of Israel, was not able to deliver him on Gilboa.
