Charles Ellicott Commentary 2 Chronicles 24:20

"And the Spirit of God came upon Zechariah the son of Jehoiada the priest; and he stood above the people, and said unto them, Thus saith God, Why transgress ye the commandments of Jehovah, so that ye cannot prosper? because ye have forsaken Jehovah, he hath also forsaken you." — 2 Chronicles 24:20 (ASV)

And the Spirit of God came upon. —Literally, clothed, invested. (See Note on 1 Chronicles 12:18.)

Zechariah the son of Jehoiada the priest. —“The priest,” i.e., the high priest, is an epithet of Jehoiada, not of Zechariah.

Which stood above the people. —Probably on the steps of the inner court of the Temple, facing the people who were assembled in the outer court.

Why transgress. —Why are you transgressing?

That ye cannot prosper. —Literally, and will not prosper.

Because ye have forsaken ... —Rather, for you have forsaken the Lord, and He has forsaken you. (Compare the similar language ascribed to the prophets Shemaiah and Azariah ben Oded, 2 Chronicles 12:5; 2 Chronicles 15:2).
