Psalm 19:7-14

The law of the Lord is perfect,
    reviving the soul;
the testimony of the Lord is sure,
    making wise the simple;
the precepts of the Lord are right,
    rejoicing the heart;
the commandment of the Lord is pure,
    enlightening the eyes;
the fear of the Lord is clean,
    enduring forever;
the rules of the Lord are true,
    and righteous altogether.
More to be desired are they than gold,
    even much fine gold;
sweeter also than honey
    and drippings of the honeycomb.
Moreover, by them is your servant warned;
    in keeping them there is great reward.

Who can discern his errors?
    Declare me innocent from hidden faults.
Keep back your servant also from presumptuous sins;
    let them not have dominion over me!
Then I shall be blameless,
    and innocent of great transgression.

Let the words of my mouth and the meditation of my heart
    be acceptable in your sight,
    O Lord, my rock and my redeemer.

James 1:22-27

But be doers of the word, and not hearers only, deceiving yourselves. For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror. For he looks at himself and goes away and at once forgets what he was like. But the one who looks into the perfect law, the law of liberty, and perseveres, being no hearer who forgets but a doer who acts, he will be blessed in his doing.

If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person's religion is worthless. Religion that is pure and undefiled before God the Father is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.

Psalm 1:2

“But his delight is in the law of the Lord, and on his law he meditates day and night.”
