David
Psalm 36:10ESV·traditional attribution

Oh, continue your steadfast love to those who know you, and your righteousness to the upright of heart!

John Calvin Reformed @genevareformer

Psalm 36 Almost all interpreters agree in supposing, that in this psalm David in general expresses his wonder and amazement at the goodness of God, because, in the exercise of his favor and mercy, he bears with the wicked, who, notwithstanding, basely contemn him. The opinion which I have formed is somewhat different.

C.H. Spurgeon Reformed Baptist @princeofpreachers

O continue thy lovingkindness unto them that know thee. We ask no more than a continuance of the past mercy. Lord, extend this grace of thine to all the days of all who have been taught to know thy faithful love, thy tenderness, thine immutability and omnipotence. As they have been taught of the Lord to know the Lord, so go on to instruct them and perfect them.

Matthew Henry Presbyterian @wholebiblehenry

David, having looked round with grief upon the wickedness of the wicked, here looks up with comfort upon the goodness of God, a subject as delightful as the former was distasteful and very proper to be set in the balance against it. Observe, I. His meditations upon the grace of God.
