1 Thessalonians 5:19-23King James Version (KJV)
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.
23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
