17 And he will [himself] go before Him in the spirit and power of Elijah, to turn back the hearts of the fathers to the children, and the disobedient and incredulous and unpersuadable to the wisdom of the upright [which is the knowledge and holy love of the will of God]–in order to make ready for the Lord a people [perfectly] prepared [in spirit, adjusted and disposed and placed in the right moral state]. [Isa. 40:3; Mal. 4:5, 6.]
18 And Zachariah said to the angel, By what shall I know and be sure of this? For I am an old man, and my wife is well advanced in years.
19 And the angel replied to him, I am Gabriel. I stand in the [very] presence of God, and I have been sent to talk to you and to bring you this good news. [Dan. 8:16; 9:21.]
20 Now behold, you will be and will continue to be silent and not able to speak till the day when these things take place, because you have not believed what I told you; but my words are of a kind which will be fulfilled in the appointed and proper time.
21 Now the people kept waiting for Zachariah, and they wondered at his delaying [so long] in the sanctuary.
22 But when he did come out, he was unable to speak to them; and they [clearly] perceived that he had seen a vision in the sanctuary; and he kept making signs to them, still he remained dumb.
23 And when his time of performing priestly functions was ended, he returned to his [own] house.
