A.T. Robertson Commentary 1 Thessalonians 5:20

"despise not prophesyings;" — 1 Thessalonians 5:20 (ASV)

Despise not prophesyings (προφητειας μη εξουθενειτε). Same construction, stop counting as nothing (εξουθενεω, ουθεν=ουδεν), late form in LXX. Plutarch has εξουδενιζω. Plural form προφητειας (accusative). Word means

forth-telling (προ-φημ) rather than

fore-telling and is the chief of the spiritual gifts (1 Corinthians 14) and evidently depreciated in Thessalonica as in Corinth later.
