concupiscence, desire, lust (after)

Boyd’s Bible Dictionary:

See LASCIVIOUSNESS

“Concupiscence” From Concise Bible Dictionary:

Undue and unlawful lust (Rom. 7:8; Col. 3:5; 1 Thess. 4:5).

“Lust, To” From Concise Bible Dictionary:

The word έπιθυμέω signifies “to desire earnestly,” and is often translated “desire,” without the thought of the desire being an evil one, as in Matthew 13:17; 1 Timothy 3:1; 1 Peter 1:12. The English word “lust” was anciently not always used in a bad sense, as it now is (see Deuteronomy 12:15 and Galatians 5:17).
