Dictionary of Biblical Words:
This is generally applies to “quenching the Spirit” (1 Thess. 5:19). The word means to “put out,” like a lamp (Matt. 25:8) or candle. Any arrangement that stops or prevents the action of the Holy Ghost in a Christian assembly would come under this head. Grieving the Spirit is somewhat different, and consists in a line or course of conduct with which He cannot go.
