The ACACIA tree, why it was chosen as a building material for the ARK of COVENANT?

The civilization of EGYPT spans back thousands of years to the days when the last great glaciers in the world were melting (10,000 BC). Hebrews were the ones who were exploited by them.
At that time spirituality played a huge role in the lives of both groups and this is depicted in the hieroglyphs that the Egyptians have left behind on the walls of their tombs and the narrative in the Scriptures in the book of Exodus in which the Hebrews are being liberated by GOD through Moses, from the Egyptian's hand.
The Egyptians were using the mighty power that the Hebrews had, given the fact that they were the chosen ones in which the power  of GOD manifested directly. However, Hebrews fall from the special status in which they were and were just conforming themselves with the way of life in the Egyptian world because of the lack of faith in their own GOD.
The ACACIA tree is the best symbol of the spiritual body that the Hebrews needed to form in order to surpass the power of the Egyptian world.
The ACACIA wood is mentioned 12 times in the Scriptures. Acacia wood is dense and extremely strong. It is a low (humble) desert tree with an impressive umbrella shaped canopy. The canopy is formed by several equal sized branches originate from one point at the soil surface. They grow outward symmetrically in all directions, at an angle of 30 degrees from the perpendicular, and create an inverted cone.
The type of spiritual body that the Hebrews needed to conform was designed by the nature of the tree itself. The tree was known for its deep roots and grew in places where the water was at great depths and exploited water stores with which other plants cannot compete.
The Egyptians were not powerful enough to reach this resources because their hearts were entrenched in the things that belonged to the physical pleasure. The Hebrews were the opposite. They were capable to choose GOD and their heart were powerful enough to reach these waters of wisdom as long as their faith and hope were really strong.
Then they could be compared as the Acacia wood, which is often mentioned in the Scriptures in the book of Exodus, in reference to objects used in the construction of the Tabernacle and in its use in the construction of the ARK of the COVENANT.
The use of this ACACIA wood resulted in the fact that this material endured for a long time. The Tabernacle was used for the next 400 years, eventually finding a resting place within the Temple in Jerusalem constructed during the reign of Solomon.
