One of the most powerful natural appetities, the craving for water or other drink. Besides its natural significance, thirst is figuratively used of strong spiritual desire. The soul thirsts for God (Ps 42:2; 63:1). Jesus meets the soul’s thirst with water of life (Joh 4:13 ff; 6:35; 7:37). It is said of the heavenly bliss, "They shall hunger no more; neither thirst any more" (Re 7:16,17; compare Isa 49:10).
