Why is Dome of the Rock on the front cover of Leningrad Codex? The octagon is the wall of Dome of the Rock and the hexagon in the middle of the octagon is the Pierced Stone.

The Leningrad Codex is an encoded information geometrically equal to the lily and the Compass Rose on the front cover of the book. The lily is the 'lily of the valleys' and the Compass Rose is the 'rose of Sharon'.

"I am the rose of Sharon, and the lily of the valleys" (Song of Solomon 2:1) "KJV"

The lily is a star hexagon representing time and the rose is a star octagon representing space, which means that the encoded information contained in the Leningrad Codex is equal to spacetime.

Space is the octet and time is equal to the eight hexagons constituting the octet.

Every space is made up of time and time is made up of space. The twenty four squares on the six sides of the hexagon in the middle of  the floor of the Dome of the Chain are the building blocks of time just as the eight hexagons constituting the octagonal wall of Dome of the Rock are the building blocks of space. Leningrad Codex cover page.

The star octagon is formed by the intersection of two squares 45° apart. This means that the octagon in the middle of the octagram is a product of the intersection of two squares. The four sides of each square are four directions of a compass, such that space is equal to 4.

Time is equal to 3 (the three sides of a triangle). The three sides are hour, minute and second, such that the triangle is a clock.

Square = 4 (Space)
= Compass

Triangle = 3 (Time)
= Clock

Square + Triangle = Space + Time
= Compass + Clock
= 4 + 3
= 7 (Spacetime)

7 is the number of God because God rested from his work of creation on the seventh day. This means that God's rest is in Spacetime.

Since the square and the triangle are geometric shapes, spacetime is equal to the various geometric patterns and designs derivable from different combinations of squares and triangles. Some products of these combinations are present in the carpet page of the Leningrad Codex.

Einstein's and other scientific descriptions of Spacetime are clearly geometry.

Time is equal to a circumscribed equilateral triangle where the circumference of the circumcircle is divided into twelve units of a clock and the three sides of the equilateral triangle are the hour, minute and second hand of a clock.

Space is equal to a circumscribed square (a cyclic quadrilateral) where the four sides of the square are the four cardinal points.

A compass clock, made up of two concentric circles, is formed by binary merger of the circumscribed equilateral triangle and the circumscribed square, thus confirming that spacetime is the sum of a compass and a clock.

The twelve hours of the clock are the twelve tribes of Israel.

The compass is the eight-sided polygon and the clock is the six sided polygon on the front cover of the Leningrad Codex, which means that the content of the book is the twelve tribes of Israel in spacetime.

The book is Israel's testimony about the only God and creator of the universe. The geometric patterns are physical manifestation of the LORD God Almighty who was in communication with the Israelites.
