Revelation 14:4

Were not defiled [ο υ κ ε μ ο λ υ ν θ η σ α ν]. The verb means properly to besmear or besmirch, and is never used in a good sense, as miainein (John 18:28; Jude 1:8), which in classical Greek is sometimes applied to staining with color. See on 1 Peter 1:4.

Virgins [π α ρ θ ε ν ο ι]. Either celibate or living in chastity whether in married or single life. See 1 Corinthians 7:1-7; 1 Corinthians 7:29; 2 Corinthians 11:2.

First - fruits [α π α ρ χ η]. See on James 1:18.
