Charles Ellicott Commentary Psalms 119:57

"Jehovah is my portion: I have said that I would observe thy words." — Psalms 119:57 (ASV)

CHETH.

You are my portion, O Lord. —This rendering is in accordance with Psalm 16:5; Psalms 73:26. But, even with these passages in view, a better rendering would be—

This is my portion, O Lord, I said (it),
To keep Your words.
