Who was the youngest person to die in the Bible?
The youngest person to die isn't named. There were many killed in the wars of the Old Testament. Herod tried to kill Christ by killing all children from Bethlehem two years of age and under (Matthew 2:16). The edict may have extended up to ten miles around Bethlehem since Rama (Mt. 2:18) is five miles north of Jerusalem. Jerusalem wouldn't have been spared.
Many other young deaths are indirectly referenced. The youngest, however, is not named.
