Is Blood Thicker Than Water?

This phrase has completely lost its original, covenant-related, meaning. Today, it is interpreted as meaning that blood-related family members are to be considered as more important than anyone else. However, the original meaning is, "The blood of the covenant is thicker than the water of the womb," or, "My relationship with those to whom I am joined in covenant is to be considered of more value than the relationship with a brother with whom I may have shared the womb."
