Psalm 49:3

A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.

Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer.

Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge.

My heart is inditing a good matter: I speak of the things which I have made touching the king: my tongue is the pen of a ready writer.

The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment.

My words shall be of the uprightness of my heart: and my lips shall utter knowledge clearly.

My doctrine shall drop as the rain, my speech shall distil as the dew, as the small rain upon the tender herb, and as the showers upon the grass:

If not, hearken unto me: hold thy peace, and I shall teach thee wisdom.

The entrance of thy words giveth light; it giveth understanding unto the simple.

My meditation of him shall be sweet: I will be glad in the LORD.
