David
Psalm 41:7ESV·traditional attribution

All who hate me whisper together about me; they imagine the worst for me.

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.

Here we have a controversy between the pleader and his God. He has been a tender friend to the poor, and yet in the hour of his need the promised assistance was not forthcoming. In our Lord's case there was a dark and dreary night in which such arguments were well befitting himself and his condition.

C.H. Spurgeon Reformed Baptist @princeofpreachers

All that hate me whisper together against me. The spy meets his comrades in conclave and sets them all a whispering. Why could they not speak out? Were they afraid of the sick warrior? Or were their designs so treacherous that they must needs be hatched in secrecy? Mark the unanimity of the wicked— all. How heartily the dogs unite to hunt the stag!
