Ezekiel 40:47-49
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.
