Definition: The word "argillite" in biblical times referred to a type of limestone that formed over thousands of years, giving it its unique smoothness and hard texture. In this context, "argillite" may have been used to refer to the soil found on Mount Ararat, which was once covered by an argillite layer. The word's meaning has evolved with time, though originally it meant a type of limestone similar in composition to sandstone, but it also referred to a specific variety. In Genesis 17:6-8, God said "And He gave the earth into your hand; and all its inhabitants became his people." This phrase means that the land is owned by God, as he has given it to humanity for the benefit of all. In this narrative context, "argillite" may have been used to refer to a land or territory originally owned by God. It also served as a metaphorical term for a specific region in biblical times when Israel had dominion over portions of the earth, including Mount Ararat and the area under its control.
