Gaster encompasses the internal abdominal cavity, covering two closely related but distinct uses: the womb in pregnancy contexts and the belly as the organ of appetite. Most NT occurrences involve conception and pregnancy—'having in the womb' (en gastri echousa) is the standard Greek idiom for being pregnant, appearing in the annunciation to Mary (Luke 1:31), the Isaianic prophecy (Matt 1:23), and warnings about end-times hardship for expectant mothers (Matt 24:19; Mark 13:17; Luke 21:23). In contrast, Titus 1:12 quotes the Cretan poet Epimenides: 'Cretans are always liars, evil beasts, lazy bellies,' where gaster means the stomach as a symbol of gluttony. Spanish 'vientre' and German 'Leib/Mutterleib' reflect this same dual range of belly and womb.
