David
Psalm 41:1ESV·traditional attribution

Blessed is the one who considers the poor! In the day of trouble the LORD delivers him;

John Calvin Reformed @genevareformer

PSALM 41 David, while he was severely afflicted by the hand of God, perceived that he was unjustly blamed by men who regarded him as one who had already been condemned and devoted to eternal destruction. Under this trial he fortifies himself by the consolation of hope. At the same time, he complains partly of the cruelty, and partly of the treachery, of his enemies.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Blessed is he that considereth the poor. This is the third Psalm opening with a benediction, and there is a growth in it beyond the first two. To search the word of God comes first, pardoned sin is second, and now the forgiven sinner brings forth fruit unto God available for the good of others.

Matthew Henry Presbyterian @wholebiblehenry

In these verses we have, I. God's promises of succour and comfort to those that consider the poor; and, 1. We may suppose that David makes mention of these with application either, (1.) To his friends, who were kind to him, and very considerate of his case, now that he was in affliction: Blessed is he that considers poor David.
