In part 10 of the Sons of Zadok teaching, Dr. Samuel Greene of Narrow Way Ministries International ministers out of Deuteronomy 10:6-8, which describes the journey of the children of Israel to where God then, in verse 8, separates the tribe of Levi to bear the ark of the covenant of the Lord. The definitions of each place they pass through gives great insight to the processes of God in His people whereby He make His choice for the priesthood.
