The answer is: Death

Exo 21:15

The Mosaic law is packed with startling statutes, and Exodus 21:15 shines an intense spotlight on parental respect. Striking a parent wasn't just viewed as a serious offense; it was deemed so grievous that the punishment was death. Now, before we start picturing historical justice systems that recognized "extreme measures," it’s essential to consider cultural context.

In ancient Israel, family hierarchy was of monumental importance, tied inextricably to community and obedience. The law sought to establish respect and honor towards parents, which echoed the broader core values of the culture—values wedged strongly in their teachings about familial loyalty and societal cohesion.

Interestingly, this law resonates with similar values in other cultures. Consider how in different societies, even today, that striking or disobeying parents could lead to severe consequences—often informal but nonetheless grave.

A fun trivia note: The fifth commandment "Honor your father and mother" (Exodus 20:12) duplicates the essence of the law in Exodus 21:15 but in a manner that speaks to reverence rather than punishment. This honoring isn't confined to merely physical behavior; it branches into respect and support for one's parents throughout their lifespan.

Moreover, unmistakable biblical figures, like King Solomon, often illustrated wisdom and discernment in understanding family dynamics. This intricate tapestry of ancient laws reflects a considerably serious treatment of familial roles, brilliantly linking obedience to survival and success within community frameworks. Isn’t it fascinating how history and scripture provide lessons in respect, and might even influence beams of thought in everyday practices?
