Then followed the ratification of the covenant. An altar was built at the foot of the mountain, and beside it twelve pillars were set up, "according to the twelve tribes of Israel," as a testimony to their acceptance of the covenant. Sacrifices were then presented by young men chosen for the service.

Derefter fulgte stadfæstelsen af pagten. Et alter blev bygget ved foden af bjerget, og ved siden af det blev der rejst tolv stenstøtter, svarende til Israels tolv stammer, som et vidnesbyrd om, at de godkendte pagten. Derpå bragte nogle udvalgte unge mænd ofre.
