Albert Barnes Commentary Psalms 119:33

"Teach me, O Jehovah, the way of thy statutes; And I shall keep it unto the end." — Psalms 119:33 (ASV)

Teach me, O Lord, the way of thy statutes - This begins a new division of the psalm, indicated by the letter He (ה h — or “h”). The word rendered “teach” means properly to throw, to cast, to hurl; and then, to teach — as if truth were thrown and scattered abroad. The sentiment is the same as in (Psalms 119:12).

And I shall keep it unto the end - Always. To the end of life. His keeping it depended on grace given to him continually to dispose and enable him to do it.
