Luke 1:16-18

Amplified Bible

¹⁶ He will turn many of the sons of Israel back [from sin] to [love and serve] the Lord their God. ¹⁷ It is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous [which is to seek and submit to the will of God]—in order to make ready a people [perfectly] prepared [spiritually and morally] for the Lord.”^(A)

¹⁸ And Zacharias said to the angel, “How will I be certain of this? For I am an old man and my wife is advanced in age.”
