Blessed are the undefiled in the way,
who walk in the law of the Lord.

They also do no iniquity:
they walk in his ways.

O that my ways
were directed to keep thy statutes!

Wherewithal shall a young man cleanse his way?
by taking heed thereto according to thy word.

I have rejoiced in the way of thy testimonies,
as much as in all riches.

I will meditate in thy precepts,
and have respect unto thy ways.

Psalm 119:1-16
