“But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.”
King James Version (KJV)
3:14 If ye have bitter zeal - True Christian zeal is only the flame of love. Even in your hearts - Though it went no farther. Do not lie against the truth - As if such zeal could consist with heavenly wisdom.
Jas 3:14 Glory not. If there is bitterness in the heart, let there be no boasting of your goodness. That would be to lie "against the truth".
