Charles Ellicott Commentary Psalms 73:16

"When I thought how I might know this, It was too painful for me;" — Psalms 73:16 (ASV)

When I thought ... —i.e., when I reflected in order to know this —when I tried to think the matter out, get at the bottom of it. (For the sense of the verb, compare Psalm 78:5; Proverbs 16:9.)

It was too painful. —See margin.
