Three comes from the one. Seven comes from the three.
Melchizedek Key (Key of Shalem) pendant contains a structure that is the base for the Seven Turn Labyrinth (diagram 2), an ancient structure found in many places throughout the world. The structure symbolizes the evolution of man from the animal stage up to the highest spiritual level.
The Book of Genesis tells the story of a meeting between Abraham the patriarch, and king Melchizadek - king of Salem. "And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the highest God (El Elyon). And he blessed him, and said, blessed be Abraham of the highest God, possessor of heaven and earth: And blessed be the highest God, which hath delivered thine enemies into thy hand. And he gave him tithes of all."
Abraham gives Melchizadek a symbolic offering of a tithe. Melchizadek is described as a high priest of God, possessor of heaven and earth. In the ancient Canaanite culture, the name "El" (which is currently in our modern times one of the Hebrew names of God) referred to the god who was the owner of Heaven while the god Baal was the owner of the earth. Therefore this appellation of Melchizadek emphasizes that the text was referring specifically to him as the priest of the One God. In spite of the idea that Abraham was the first to embrace the One God, we see here, that this concept was already in existence.
The Hebrew engraving on one side of Melchizedek Key pendant translates as: "Three comes from one". On the opposite side, the engraving translates as: "Seven comes from the three". The numerological value of the word "Shalem" adds up to 371 which connects us to the Enneagram structure on one of the facets of the pendant.
The teeth of the key form the Hebrew letter "PE", whose literal translation is "mouth through which we speak". The Creator in Genesis "speaks" and creates in this way. If you observe closely you can see the Hebrew letter "Beit" within the Hebrew letter "PE". "Beit" is the first letter of the words "BERESHEET" - Genesis and the "Briaa" - Creation.
