 the gift of one's blood for a covenant? Well, because the covenant is making a family and blood is always deeply related to being family. I mean, to this day, we say he's blood to me, right? That means, you know, he's my cousin or something. He's a family member. But when our Lord drew at the Last Supper, says this cup is the new covenant in my blood, he's harking back to the first time that we talk about the blood of the covenant, which is all the way back with Moses.
