Which came first, it or God's Law from Exodus 20 through Exodus 24?
What does documented history say?

Tiglath-pileser I and Thutmose III

Another king in the Calah list is very significant — Tiglath-pileser I.
His reign commences in 991, almost the exact midpoint of Solomon's reign.
Tiglath-pileser wrote in his annals that he beheaded the kings of Meshech at that time.
"In the beginning of my reign, twenty thousand men of the land of Mushki and their five kings,
who for fifty years had held the lands of Alzi and Purukuzzi, which (in former times) had paid tribute and tax unto Assur, my lord, and no king had vanquished them in battle," he beheaded.
("Ancient Records of Assyria and Babylonia", by Daniel David Luckenbill, vol. I, page 74.)
What is the significance of the 50 years from 1041 to 991 when Tiglath-pileser I defeated Meshech (Musku)?
In year 32 of Hammurabi (1041-1040) he and his allies defeated Assyria and annexed it to his expanding realm!
(See Van der Meer's "Chronology of Ancient Western Asia", page 30.)
It was exactly 50 years between Hammurabi's victory and Assyria's return to power.

In the latter days of Tiglath-pileser I's reign Assyria was again defeated and conquered.
Who was the conqueror? Thutmose III!
In his annals Thutmose recorded receipt of tribute from Assur.
"The tribute of the chief of Assur" (Breasted's "Ancient Records", vol. II, sec. 446).

In conclusion.
The first king of the Calah line — Ninurta-apil-Ekur — began his sole rule in 1058 (near the end of the reign of King Saul of Israel).
The SDAS King List assigns a 13-year reign to him, implying a 10-year joint rule with a predecessor.

A cast of the SDAS list is in the Horn Museum of Andrews University (the original was returned to the Middle East).

God's Law came first and the Code of Hammurabi came later and was derived FROM God's Law.

There’s no mention of God in the Constitution. The notion that it’s a religious document is simply false.

Oh and you have the wrong date for H there. He lived around 1750 BC which predates the date generally given for the Exodus. The Bible was probably influenced by the Code of H.
