Infirmity
New TestamentVine's Expository Dictionary of Biblical Words
Definition
lit., "want of strength" (a, negative, sthenos, "strength"), "weakness," indicating inability to produce results, is most frequently translated "infirmity," or "infirmities;" in Rom 8:26, the RV has "infirmity" (AV, "infirmities"); in 2Co 12:5, 2Co 1:12-10, "weaknesses" and in 2Co 11:30, "weakness" (AV, "infirmities"); in Luk 13:11 the phrase "a spirit of infirmity" attributes her curvature directly to satanic agency. The connected phraseology is indicative of trained medical knowledge on the part of the writer.
akin to No. 1, is found in the plural in Rom 15:1, "infirmities," i.e., those scruples which arise through weakness of faith. The strong must support the infirmities of the weak (adunatos) by submitting to self-restraint.
Note: In Luk 7:21, AV, nosos, "a disease," is translated "infirmities" (RV, "diseases").
