EZK 8:16

16 And He brought me into the khatzer Beis Hashem hapenimit, and, hinei, at the petach [(entrance)] of the Heikhal Hashem, between the Ulam and the Mizbe'ach, were about five and twenty ish, with their backs toward the Heikhal Hashem, and their faces toward the east; and they bowing down toward the east worshiping the sun.
