Hebrews 13:4-6

13:4 Marriage must be honored among all and the marriage bed kept undefiled, for God will judge sexually immoral people and adulterers. 13:5 Your conduct must be free from the love of money and you must be content with what you have, for he has said, “I will never leave you and I will never abandon you.” ¹  13:6 So we can say with confidence, “The Lord is my helper, and ²  I will not be afraid. What can man do to me?” ³

[13:6]  ¹ tc Some important mss (א* C* P 0285^vid 33 1175 1739 pc lat) lack καί (kai), but because the omission conforms to the wording of Ps 118:6 (117:6 LXX), it is suspect.
