G‑d also taught Moses the laws pertaining to damages caused by a person’s animals or property, including a pit that someone digs in the public domain.
Care in Receiving; Care in Giving
וְכִי יִפְתַּח אִישׁ בּוֹר אוֹ כִּי יִכְרֶה אִישׁ בֹּר . . . וְנָפַל שָׁמָּה שּׁוֹר אוֹ חֲמוֹר: בַּעַל הַבּוֹר יְשַׁלֵּם וגו': (שמות כא:לג–לד)
If a person uncovers or digs a pit . . . and an ox or donkey falls into it, the one responsible for the pit must pay [for the damage]. Exodus 21:33-34

The same law that applies to a pit (i.e., a sunken hazard) applies to a raised barrier or other obstacle (i.e., a protruding hazard).

Spiritually, a pit represents our ability to receive and a protrusion represents our ability to give. Properly used, these abilities can be beneficial; without proper supervision, however, they may cause damage. If we give and receive haphazardly – not paying heed to what or how much we are giving or receiving, or to whom we are giving or from whom we are receiving – we will become a danger to society. But if we choose to accept only positive influences and spread only positivity throughout our surroundings, we will become a source of blessing to all around us.1
