The Hebrew never says a covenant is made. It says a covenant is cut, karat brit. The verb is violent on purpose. In the Ancient Near East, two parties ratified an agreement by cutting animals in half, laying the pieces in two rows, and walking together down the bloody aisle between them. The unspoken oath was carried in the body: let it be done to me as it was done to these animals if I break my word. The cut pieces were the self-curse made visible.

This is why Genesis 15 is the master key to the whole Bible. HaShem tells Avraham to cut the animals, and then, while Avraham lies asleep, HaShem alone passes between the pieces as a smoking fire pot and a flaming torch. He walks both sides of the aisle, the divine and the human, because the human could not. When Yeshua lifts the cup and says, this is the new covenant in My blood, He is cutting a brit in His own body. The cross is karat brit, not a courtroom.
