Chronicles II 20:14 Meaning and Commentary

2 Chronicles 20:14

Then upon Jahaziel, the son of Zechariah, the son of Benaiah,
the son of Jehiel, the son of Mattaniah, a Levite, of the sons of
Asaph
Being a man of some note, though a Levite, his genealogy is given: came the Spirit of the Lord in the midst of the congregation;
the spirit of prophecy from the Lord, as the Targum, as it was; for he foretold the victory that should be obtained over the enemy, and that without fighting, yea, the particular place where they should meet them; and this came upon him suddenly, while he was in the midst of the congregation, while he and they were waiting upon the Lord, and perhaps had never prophesied before; or if he had, prophecy did not come according to the will of man, but by the will of God; the Spirit of God in that, as in other instances, is like the wind that blows when and where it listeth.
