Charles Ellicott Commentary Luke 1:17

"And he shall go before his face in the spirit and power of Elijah, to turn the hearts of the fathers to the children, and the disobedient [to walk] in the wisdom of the just; to make ready for the Lord a people prepared [for him]." — Luke 1:17 (ASV)

To the wisdom of the just.—The margin, by the wisdom, is undoubtedly the right rendering.
