Ezekiel 40:46-49

40:46 and the chamber which faces north is for the priests who keep charge of the altar. These are the descendants of Zadok, from the descendants of Levi, who may approach the Lord to minister to him.” 40:47 He measured the court as a square 175 feet long and 175 feet wide; the altar was in front of the temple.

40:48 Then he brought me to the porch of the temple and measured the jambs of the porch as 8¾ feet on either side, and the width of the gate was 24½ feet and the sides were 5¼ feet on each side. 40:49 The length of the porch was 35 feet and the width 19¼ feet; steps led up to it, and there were pillars beside the jambs on either side.
