PSALMS 119:7-11

7 I will praise you with an upright heart
    as I learn your righteous laws.
8 I will obey your decrees;
    do not utterly forsake me.
9 How can a young person
stay on the path of purity?
    By living according to your word.
10 I seek you with all my heart;
    do not let me stray from your commands.
11 I have hidden your word in my heart
    that I might not sin against you.
