Moses
Psalm 77:19BSB·traditional attribution

Your path led through the sea, Your way through the mighty waters, but Your footprints were not to be found.

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

Thy way is in the sea. Far down in secret channels of the deep is thy roadway; when thou wilt thou canst make a sea a highway for thy glorious march. And thy path in the great waters. There, where the billows surge and swell, thou still dost walk; Lord of each crested wave. And thy footsteps are not known. None can follow thy tracks by foot or eye.

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.
