The blood of the covenant is thicker than the water of the womb.
Almost everyone believes “blood is thicker than water” means that family is more important than friendships or that family bonds are closer than friendship.
The full quote, however, is: “The blood of the covenant is thicker than the water of the womb.” The original meaning of the phrase was blood shed on the battlefield creates a stronger bond between soldiers than simple familial or genetic ties.
In principle, it means friendships you choose are stronger than genetic ties to your family.
And so it is with many things in life. So many things we take for granted are actually not what they appear to be.
