BLESSED are they that are perfect in the way, who walk in the law of the Lord.
Blessed are they that keep his testimonies, that seek him with the whole heart.
Yea, they do no unrighteousness; they walk in his ways.
Thou hast commanded us thy precepts, that we should observe them diligently.
Oh that my ways were established to observe thy statutes!
Then shall I not be put to shame.
Wherewith shall a young man cleanse his way?
By taking heed thereto according to thy word.
With my whole heart have I sought thee:
Oh let me not wander from thy commandments.
Thy word have I laid up in my heart, that I might not sin against thee.
Blessed art thou, O Lord: Teach me thy statutes.
With my lips have I declared all the ordinances of thy mouth.
I have rejoiced in the way of thy testimonies, as much as in all riches.
I will meditate on thy precepts, and have respect unto thy ways.
I will delight myself in thy statutes: I will not forget thy word.
I WILL judge you; every one according to his ways, saith the Lord.
Return ye, and turn yourselves from all your transgressions; so iniquity shall not be your ruin.
Cast away from you all your transgressions, wherein ye have transgressed;
And make you a new heart and a new spirit: for why will ye die;
For I have no pleasure in the death of him that dieth, saith the Lord,
Wherefore turn yourselves, and live.
