Reference for Berakhot 20:32

Ten wonders were wrought for our ancestors in the Temple: [1] no woman miscarried from the odor of the sacred flesh; [2] the sacred flesh never became putrid; [3] no fly was ever seen in the slaughterhouse; [4] no emission occurred to the high priest on the Day of Atonement; [5] the rains did not extinguish the fire of the woodpile; [6] the wind did not prevail against the column of smoke; [7] no defect was found in the omer, or in the two loaves, or in the showbread; [8] the people stood pressed together, yet bowed down and had room enough; [9] never did a serpent or a scorpion harm anyone in Jerusalem; [10] and no man said to his fellow: the place is too congested for me to lodge overnight in Jerusalem.
