 The Koine Greek dialect is how the New Testament was written, and this is the word that was used for what we translate repent, metanoeo. In 2 Peter 3, 9, again, the Bible says, The Lord is not slack concerning his promise, as some count slackness, but is longsuffering towards us, not willing that any should perish, but that all should come to repentance. All should come to repentance. And we have another Greek word, metanoeo.
