Yechezkel 40:3

Orthodox Jewish Bible

³ And He brought me there, and, hinei, there was an ish, whose appearance was like the appearance of nechoshet, with a cord of linen in his yad, and a keneh hamiddah (measuring rod); and he [the angelic being] stood in the sha’ar (i.e., the Eastern Gate; see further 43:1-5; 44:1-3; Hashem’s glory enters and exits here and Moshiach, see 44:3).
