19 Quench not the Spirit.
20 Despise not prophesyings.
21 Prove all things; hold fast that which is good.
22 Abstain from all appearance of evil.
1 Thessalonians 5:19-22
In the NLT it says:
19 Do not stifle the Holy Spirit. 20 Do not scoff at prophecies, 21 but test everything that is said. Hold on to what is good. 22 Stay away from every kind of evil.
In the Amplified Bible that is expanded as:
19 Do not quench (suppress or subdue) the [Holy] Spirit;
20 Do not spurn the gifts and utterances of the prophets [do not depreciate prophetic revelations nor despise inspired instruction or exhortation or warning].
21 But test and prove all things [until you can recognize] what is good; [to that] hold fast.
22 Abstain from evil [shrink from it and keep aloof from it] in whatever form or whatever kind it may be.
