“For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.”
King James Version (KJV)
2:21 The commandment - The whole law of God, once not only delivered to their ears, but written in their hearts.
2Pe 2:21 For it had been better, etc. To other sins there is then added the sin of rejecting the way of righteousness after an experimental knowledge of it.
