Ephesians 5:3

5:3 But ¹  among you there must not be either sexual immorality, impurity of any kind, ²  or greed, as these are not fitting for the saints. ³ 

Hebrews 13:4

13:4 Marriage must be honored among all and the marriage bed kept undefiled, for God will judge sexually immoral people and adulterers.

[5:3]  ¹ tn The term “But” translates the δέ (de) in a contrastive way in light of the perfect obedience of Jesus in vv. 1-2 and the vices mentioned in v. 3.

[5:3]  ² tn Grk “all impurity.”

[5:3]  ³ tn Grk “just as is fitting for saints.” The καθώς (kaqws) was rendered with “as” and the sense is causal, i.e., “for” or “because.” The negative particle “not” (“for these are not proper for the saints”) in this clause was supplied in English so as to make the sense very clear, i.e., that these vices are not befitting of those who name the name of Christ.
