The "Slaughter of the Innocents" refers to a biblical event described in the Gospel of Matthew. It recounts how King Herod ordered the massacre of all male infants in Bethlehem under the age of two. This act was intended to eliminate the newborn Jesus, whom Herod viewed as a threat to his throne after hearing of the prophecy regarding a new king. This event is often interpreted as a demonstration of Herod's cruelty and the lengths to which he would go to maintain power. It is commemorated in Christian tradition and serves as a reminder of the suffering of innocents throughout history.
