Charles Ellicott Commentary Psalms 63:8

"My soul followeth hard after thee: Thy right hand upholdeth me." — Psalms 63:8 (ASV)

My soul ... —Literally, my soul clung to you, combining two ideas. (Compare to Jeremiah 42:16.) The English phrase, “hung upon you” (compare to the Prayer-Book version), exactly expresses it.

For “depths,” or “abysses of the earth,” compare to Psalms 139:15; Ephesians 4:9. It means the underworld of the dead.
