MNT(i)
8 Now while Zachariah was acting as priest before God in the due course of his class, it fell to his lot, according to the custom of priesthood,
9 to enter into the sanctuary of the Lord and to burn incense.
10 And the whole multitude of the people were without, praying at the hour of incense.
11 Then there appeared to him an angel of the Lord, standing on the right side of the altar of incense.
