Every Word of God is tried and purified; He is a shield to those who trust and take refuge in Him.
As for God, His way is perfect:
The LORD’s word is flawless;
He shields all who take refuge in Him.2
And the words of the Lord are flawless,like silver purified in a crucible, like gold refined seven times. Psalm 12:6
Every word of God is pure; He is a shield unto them that put their trust in Him. Proverbs 30:5
