Psalm 88:6 (ESV)

6 You have put me in the depths of the pit, in the regions dark and deep.

Again, Heman sees God at work. The Lord has thrown him into a bottomless pit from which he cannot escape. He is buried in deep and dark waters. What happens to him is like the floods that once covered the Egyptian army (Exodus 15:5). And yet, he does not remain silent. I called on your name, O Lord, from the depths of the pit (Lamentations 3:55).

Apparently, his faith cannot be smothered. He speaks to the Lord about what is happening to him. He refuses to believe that God is outside of all the dreadful things he must experience.

He is like the one who confesses (Heidelberg Catechism, q/a 27) that God’s providence is that leaf and blade, rain and drought, fruitful and barren years, food and drink, health and sickness, riches and poverty, indeed, all things, come to us not by chance, but by his fatherly hand.
