Your statutes are wonderful;
    therefore I obey them.
The unfolding of your words gives light;
it gives understanding to the simple.
I open my mouth and pant,
longing for your commands.
Turn to me and have mercy on me,
as you always do to those who love your name.
Direct my footsteps according to your word;    
let no sin rule over me.
Redeem me from human oppression,
    that I may obey your precepts.
Make your face shine on your servant
    and teach me your decrees.
Streams of tears flow from my eyes,
    for your law is not obeyed.

(Psalm 119:129-136, NIV)
