Context
46 The room which faces toward the north is for the priests who perform the duty of the altar. These are the sons of Zadok, who from among the sons of Levi come near to the LORD to minister to him.”
47 He measured the court, one hundred cubits long and one hundred cubits wide, square. The altar was before the house.
48 Then he brought me to the porch of the house, and measured each post of the porch, five cubits on this side, and five cubits on that side. The width of the gate was three cubits on this side and three cubits on that side.
