1: ἀπορφανίζω
(Strong's #642 — Verb — aporphanizomai — ap-or-fan-id'-zo )

lit., "to be rendered an orphan" (apo, "from," with the thought of separation, and orphanos, "an orphan"), is used metaphorically in 1—Thessalonians 2:17 (AV, "taken from;" RV, "bereaved"), in the sense of being "bereft" of the company of the saints through being compelled to leave them (cp. the similes in 7 and 11). The word has a wider meaning than that of being an orphan.
