Luke 1:17

And he shall go before him Shall go before the Messiah. The English version should have added, "in His (God's) presence" (ἐνώπιον αὐτοῦ).

in the spirit and power of Elias From the last words of Malachi (Luke 4:4-6; Luke 3:1), the Jews universally believed (as they do to this day) that Elijah would visibly return to earth as a herald of the Messiah. It required the explanation of our Lord to open the eyes of the Apostles on this subject. "This is Elias which was for to come," Matthew 11:14. "Elias truly shall first come and restore all things … Then the disciples understood that He spake unto them of John the Baptist," Matthew 17:10-14. The resemblance was partly in external aspect (2 Kings 1:8; Matthew 3:4); and partly in his mission of stern rebuke and invitation to repentance (1 Kings 18:21; 1 Kings 21:20).

to turn the hearts of the fathers to the children Rather, of fathers to children; i. e. as in the original meaning of Malachi, to remedy disunion and restore family life.

to the wisdom Rather, in or by the wisdom.
