David
Psalm 56:13BSB·traditional attribution

For You have delivered my soul from death, and my feet from stumbling, that I may walk before God in the light of life.

John Calvin Reformed @genevareformer

PSALM 56 In this psalm David mixes complaint with prayer, and assuages the distress of his mind by meditation upon the mercy of God. He pray, that he may experience the divine help under the persecutions to which he was subjected by Saul, and his other enemies; and expresses his confidence of success.

C.H. Spurgeon Reformed Baptist @princeofpreachers

For thou hast delivered my soul from death. His enemies were defeated in their attempts upon his life, and therefore he vowed to devote his life to God. Wilt not thou deliver my feet from falling? One mercy is a plea for another, for indeed it may happen that the second is the necessary complement of the first.

Matthew Henry Presbyterian @wholebiblehenry

Several things David here comforts himself with in the day of his distress and fear. I. That God took particular notice of all his grievances and all his griefs, Psa 56:8. 1. Of all the inconveniences of his state: Thou tellest my wanderings, my flittings, so the old translation.
