“The law of the LORD is perfect”
God’s word is perfect
That thy trust may be in the LORD, I have made known to thee this day, even to thee. Have not I written to thee excellent things in counsels and knowledge, That I might make thee know the certainty of the words of truth; that thou mightest answer the words of truth to them that send unto thee?
Thy word is true from the beginning: and every one of thy righteous judgments endureth for ever.
Thou art near, O LORD; and all thy commandments are truth.
Thy righteousness is an everlasting righteousness, and thy law is the truth.
Sanctify them through thy truth: thy word is truth.
All the words of my mouth are in righteousness; there is nothing froward or perverse in them. Proverbs 8:8
Therefore I esteem all thy precepts concerning all things to be right; and I hate every false way.
Thy testimonies that thou hast commanded are righteous and very faithful.
My tongue shall speak of thy word: for all thy commandments are righteousness.
Thy word is very pure: therefore thy servant loveth it.
Every word of God is pure: he is a shield unto them that put their trust in him.
The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
And this voice which came from heaven we heard, when we were with him in the holy mount. We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: Knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
II Peter 1:18-21
The works of his hands are verity and judgment; all his commandments are sure. They stand fast for ever and ever, and are done in truth and uprightness.
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
I Peter 1:23
If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
The law of the LORD is perfect, converting the soul:
the testimony of the LORD is sure, making wise the simple.
The statutes 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 for ever:
the judgments of the LORD are true and righteous altogether.
