1: ὀλιγόψυχος
(Strong's #3642 — Adjective — oligopsuchos — ol-ig-op'-soo-khos )

lit., "small-souled" (oligos, "small," psuche, "the soul"), denotes "despondent;" then, "fainthearted," 1—Thessalonians 5:14 , RV, for the incorrect AV, "feeble-minded." In the Sept., similarly, in a good sense, Isaiah 57:15 , "who giveth endurance to the fainthearted," for RV, "to revive the spirit of the humble;" in a bad sense, Proverbs 18:14 , "who can endure a fainthearted man?"
