Luke 1:10

Multitude. Gr. plethos, a favorite word with Luke, who uses it 25 times, as compared with 7 times by all the other NT writers combined. Some commentators have suggested that Zacharias was officiating at the morning service; others think it was the evening service. In the time of Christ the morning sacrifice was offered about 9 o’clock and the evening sacrifice about 3 o’clock. At either of these times a throng of considerable size might gather (see Acts 2:6, 15). Perhaps the aged and pious Simeon and Anna (see on Luke 2:25, 36) mingled, unnoticed, in the group of worshipers at this very service and lifted their hearts in prayer for the coming of the Messiah.

Without. That is, outside the sanctuary, but within the sacred courts of the Temple.
