Moses
Psalm 115:17BSB·traditional attribution

It is not the dead who praise the LORD, nor any who descend into silence.

John Calvin Reformed @genevareformer

PSALM 115 It is obvious that this psalm was penned when the Church was deeply afflicted. Unworthy as they are to be heard by God, the faithful, nevertheless, offer up supplications to him for deliverance, lest his holy name might be exposed to scorn and reproach among the heathen.

C.H. Spurgeon Reformed Baptist @princeofpreachers

The dead praise not the Lord —So far as this world is concerned. They cannot unite in the Psalms and hymns and spiritual songs with which the church delights to adore her Lord. The preacher cannot magnify the Lord from his coffin, nor the Christian worker further manifest the power of divine grace by daily activity while he lies in the grave. Neither any that go down into silence.

Matthew Henry Presbyterian @wholebiblehenry

In these verses, I. We are earnestly exhorted, all of us, to repose our confidence in God, and not suffer our confidence in him to be shaken by the heathens' insulting over us upon the account of our present distresses.
