For those who want to see it from the bible, here is how to make a covenant with God; followed by the 'plain English' translation..
Ge15:9 And he said unto him, Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon. Ge15:10 And he took unto him all these, and divided them in the midst, and laid each piece one against another: but the birds divided he not. Ge15:11 And when the fowls came down upon the carcases, Abram drove them away. Ge15:12 And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him. Ge15:13 And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; Ge15:14 And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance. Ge15:15 And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. Ge15:16 But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full. Ge15:17 And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces. Ge15:18 In the same day the LORD made a covenant with Abram,...
Gen 15:9,10 God tells Abram how to make a blood oath ritual. Cut the critters in half and lay them close to each other.
Gen 15:11 Abram screws up by starting his blood ritual in the morning. By mid-day the buzzards are coming around the smelly, dead bodies; while Abram waits for God to show up.
Gen 15:12 Abram goes to sleep (or passes out from the smell).
Gen 15:13-16 God makes His oath in a vision or dream.
Gen 15:17 God seals this oath by walking between the carcass's in the form of 'a smoking furnace, and a burning lamp that passed between those pieces'. God DOES NOT like to get His feet dirty.
Gen 15:18 This is how you make a covenent.
WARNING: Despite these clear instructions on covenant-making, the Author, that is, God; will not come to your rescue if you should start chain-sawing livestock!!! You will rot in jail after having your head examined. DO NOT TRY THIS AT HOME.
