Moses
Psalm 77:12BSB·traditional attribution

I will reflect on all You have done and ponder Your mighty deeds.

John Calvin Reformed @genevareformer

PSALM 77 Whoever was the penman of this psalm, the Holy Spirit seems, by his mouth, to have dictated a common form of prayer for the Church in her afflictions, that even under the most cruel persecutions the faithful might not fail to address their prayers to heaven.

C.H. Spurgeon Reformed Baptist @princeofpreachers

I will meditate also of all thy work. Sweet work to enter into Jehovah's work of grace, and there to lie down and ruminate, every thought being absorbed in the one precious subject. And talk of thy doings. It is well that the overflow of the mouth should indicate the good matter which fills the heart.

Matthew Henry Presbyterian @wholebiblehenry

The psalmist here recovers himself out of the great distress and plague he was in, and silences his own fears of God's casting off his people by the remembrance of the great things he had done for them formerly, which though he had in vain tried to quiet himself with (Psa 77:5, Psa 77:6) yet he tried again, and, upon this second trial, found it not in vain.
