Luke 1:18-20

Mace(i) 18 But Zacharias said to the angel, by what sign shall I know this? for I am old, and my wife is of a great age. 19 the angel replied, I am Gabriel, who attend in the presence of God, and am sent to communicate to you this agreeable message. 20 you shall now become dumb and not recover your speech, till the very day when these things shall happen; because you distrusted my words, which in due time shall have their effect.
