⁷ I will praise You with an upright heart when I learn Your righteous judgments.

⁸ I will keep Your statutes; do not utterly forsake me.

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.

¹¹ I have hidden Your word in my heart that I might not sin against You.
