Saw a post that triggered a wild spirit journey of remembrance.

To make a covenant anciently they parted certain animals and 'passed through' the parts, then they partook of [consumed] their part. This was a ritual of purification and of covenant.

See here esp. v. 9-10, 17-18

Jeremiah explicitly supports this too; as do many other accounts in the scripture and in history all over the world, they attest to this tradition of parting a sacrificial animal [body] and passing through the parts and blood as a covenantal and a purification ritual.

This connected the dots to the Covenant with Israel as the Waters of the Red Sea [and various bodies of water later] parting and the purified 'passing through' - or back it up and transpose this idea to the marking of the door posts with the blood of the Lamb at 'passover'

Look now to the Baptismal covenant, a purification covenant [for the remission of sins], a symbolic "passing through" to our 3rd Estate and future resurrected life full of the purifying Holy Spirit of the Celestial Kingdom (as the Gift of the Holy Ghost).

The Priesthood 'parts' the bread and 'divides' the water, 'passing it to' the Saints to renew their Baptismal covenants by 'partaking' (consuming) the symbolic body and passing through the symbolic blood of the Lamb of God. The Divine Body and eternal atoning sacrifice.
