Moses
Psalm 69:21ESV·traditional attribution

They gave me poison for food, and for my thirst they gave me sour wine to drink.

John Calvin Reformed @genevareformer

PSALM 69 There is a close resemblance between this psalm and the twenty-second. In the opening verses, David complains of the barbarous cruelty of his enemies, and of the grievous wrongs which they had inflicted upon him. The particular enemies of whom he speaks are uncertain; some referring the occasion of the composition of the psalm to his persecution by Saul, and others to the rebellion of Absalom.

C.H. Spurgeon Reformed Baptist @princeofpreachers

They gave me also gall for my meat. This was the sole refreshment cruelty had prepared for him. Others find pleasure in their food, but his taste was made to be an additional path of pain to him. And in my thirst they gave me vinegar to drink. A criminal's draught was offered to our innocent Lord, a bitter portion to our dying Master.

Matthew Henry Presbyterian @wholebiblehenry

David had been speaking before of the spiteful reproaches which his enemies cast upon him; here he adds, But, as for me, my prayer is unto thee. They spoke ill of him for his fasting and praying, and for that he was made the song of the drunkards; but, notwithstanding that, he resolves to continue praying.
