David
Psalm 26:2ESV·traditional attribution

Prove me, O LORD, and try me; test my heart and my mind.

John Calvin Reformed @genevareformer

PSALM 26. This psalm, for the most part, is similar to the preceding. The prophet, oppressed with numerous wrongs, and finding no succor in the world, implores the aid of God, entreating him to undertake the cause of a man unrighteously afflicted, and to assert his innocence.

There are three modes of trial here challenged, which are said in the original to refer to trial by touch, trial by smell, and trial by fire. The psalmist was so clear from the charge laid against him, that he submitted himself unconditionally to any form of examination which the Lord might see fit to employ. Examine me, O Lord.

Matthew Henry Presbyterian @wholebiblehenry

It is probable that David penned this psalm when he was persecuted by Saul and his party, who, to give some colour to their unjust rage, represented him as a very bad man, and falsely accused him of many high crimes and misdemeanors, dressed him up in the skins of wild beasts that they might bait him.
