text:  This sin, like the others he was now going to mention in this passage, are indications that the Christian, the believer, has quenched and grieved the Holy Spirit. The word bitterness is a Greek word pronounced pikria. It's spelled P-I-K-R-I-A. That's the original manuscript, the original writing, not the English, as it was written in the original Greek New Testament, the Koine Greek language. The word bitterness is pikria.
