David
Psalm 88:3ESV·traditional attribution

For my soul is full of troubles, and my life draws near to Sheol.

John Calvin Reformed @genevareformer

PSALM 88 This psalm contains very grievous lamentations, poured forth by its inspired penman when under very severe affliction, and almost at the point of despair. But he, at the same time, whilst struggling with sorrow, declares the invincible steadfastness of his faith; which he displayed in calling upon God to deliver him, even when he was in the, deep darkness of death.

C.H. Spurgeon Reformed Baptist @princeofpreachers

For my soul is full of troubles. I am satiated and nauseated with them. Like a vessel full to the brim with vinegar, my heart is filled up with adversity till it can hold no more. He had his house full and his hands full of sorrow; but, worse than that, he had his heart full of it. Trouble in the soul is the soul of trouble.

Matthew Henry Presbyterian @wholebiblehenry

It should seem, by the titles of this and the following psalm, that Heman was the penman of the one and Ethan of the other. There were two, of these names, who were sons of Zerah the son of Judah, Ch1 2:4, Ch1 2:6. There were two others famed for wisdom, Kg1 4:31, where, to magnify Solomon's wisdom, he is said to be wiser than Heman and Ethan.
