Psalm 119:7-9

Amplified Bible

⁷ 
I will give thanks to You with an upright heart,
When I learn [through discipline] Your righteous judgments [for my transgressions].
⁸ 
I shall keep Your statutes;
Do not utterly abandon me [when I fail].

⁹ 
How can a young man keep his way pure?
By keeping watch [on himself] according to Your word [conforming his life to Your precepts].
