Strong's Number 5594

Strong's Concordance - Greek #G5594

ψύχω psucho {psoo'-kho} A primary verb; to breathe (voluntarily but gently; thus differing on the one hand from G4154, which denotes properly a forcible respiration; and on the other from the base of G0109, which refers properly to an inanimate breeze), that is, (by implication of reduction of temperature by evaporation) to chill (figuratively).
