Psalms 119:11

⁹ How can a young man keep his way pure? By guarding it according to Your word.

¹⁰ With all my heart I have sought You; do not let me stray from Your commandments.

I have hidden Your word in my heart that I might not sin against You.

¹² Blessed are You, O LORD; teach me Your statutes.

¹³ With my lips I proclaim all the judgments of Your mouth.

Do read the surrounding verses too, because the context often says more than a single verse.
