Salmo 119:9-16

How can a young person stay on the path of purity?
By living according to your word.
I seek you with all my heart;
do not let me stray from your commands.
I have hidden your word in my heart
that I might not sin against you.
Praise be to you, LORD;
teach me your decrees.
With my lips I recount
all the laws that come from your mouth.
I rejoice in following your statutes
as one rejoices in great riches.
I meditate on your precepts
and consider your ways.
I delight in your decrees;
I will not neglect your word.
