the Priesthood

The priesthood of Ancient Israel was the class of male individuals, who, according to the Hebrew Bible, were patrilineal descendants from Aaron, who served in the Tabernacle, Solomon's Temple and Second Temple until the destruction of Jerusalem in 70 CE.

According to the Hebrew Bible, Solomon's Temple, also known as the First Temple, was the Holy Temple in ancient Jerusalem before its destruction by Nebuchadnezzar II after the Siege of Jerusalem of 587 BCE and its subsequent replacement with the Second Temple in the 6th century BCE.

Hebrew Bible or Hebrew Scriptures is the term used by biblical scholars to refer to the Tanakh, the canonical collection of Jewish texts, which is the common textual source of several canonical editions of the Christian Old Testament.

The Tabernacle, according to the Hebrew Bible, was the portable earthly dwelling place of God amongst the children of Israel from the time of the Exodus from Egypt through the conquering of the land of Canaan.
