VII. 'Way' or 'Walk' of Blood (5th Step)

Both representatives walk to and fro between the pieces, in a figure-8, twice (Note: The symbol for infinity is a figure-8 on its side. Can this be its origin?). Then both parties stop and swear unto death while standing in the midst of the blood, swearing by G-d (thus making G-d their 3rd party) to kill the covenant breaker and his seed after him if the terms of the covenant are breached.

A. Marriage

B: Torah

The Glory of the L-rd passing through the pieces during the covenant ceremony between G-d and Father Abraham:

And it came to pass, when the sun went down and it was dark, that behold, there appeared a smoking oven and a burning torch that passed between those pieces. (Gen 15:17)

This is the first appearance, in Scripture of the Shekhinah (Glory of G-d, the manifestation of His Divine Presence), as described here, also:

And the L-rd went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night. He did not take away the pillar of cloud by day or the pillar of fire by night {from} before the people. (Ex 13:21,22)

There is none greater than G-d, so He swears by Himself:

Remember Abraham, Isaac, and Israel, Your servants, to whom You swore by Your own self, and said to them, "I will multiply your descendants as the stars of heaven; and all this land that I have spoken of I give to your descendants, and they shall inherit {it} forever." (Ex 32:13)

For when G-d made a promise to Abraham, because He could swear by no one greater, He swore by Himself, saying, "Surely blessing I will bless you, and multiplying I will multiply you." (Heb 6:13,14)

"But if you will not hear these words, I swear by Myself," says the L-rd, "that this house shall become a desolation." (Jer 22:5)

C. Stones of Remembrance

Often a large stone or pile of stones is set up to bear witness also to the oath, as in the covenant cut between Jacob and Laban:

"Now therefore, come, let us make a covenant, you and I, and let it be a witness between you and me." So Jacob took a stone and set it up {as} a pillar. Then Jacob said to his brethren, "Gather stones." And they took stones and made a heap, and they ate there on the heap. Laban called it Jegar Sahadutha, but Jacob called it Galeed. And Laban said, "This heap {is} a witness between you and me this day." Therefore its name was called Galeed, also Mizpah, because he said, "May the L-rd watch between you and me when we are absent one from another." (Gen 31:44-49)
