John Gill Commentary Ezekiel 11:5

"And the Spirit of Jehovah fell upon me, and he said unto me, Speak, Thus saith Jehovah: Thus have ye said, O house of Israel; for I know the things that come into your mind." — Ezekiel 11:5 (ASV)

And the spirit of the Lord fell upon me
In an extraordinary manner, and afresh, and enlightened his mind, and showed him things that should come to pass; and filled him with boldness and courage to declare them.

The Targum interprets it of the spirit of prophecy: and said unto me, speak ;
what I shall show and put into your mouth, that speak out; be not afraid, but boldly declare all that I give you in commission to say:

thus saith the Lord, thus have you said, O house of Israel ;
as in (Ezekiel 11:3) ; which perhaps was said in secret, and spoken privately, but known by the Lord; and it was not only the princes that said it, but the whole body of the people joined in with it, and agreed to it; though it is very probable they were influenced by the former:

for I know the things that come into your mind, [everyone of] them ;
not only their scoffing words, but the thoughts of their hearts; not one of them escaped the knowledge of God; the consideration of which should command an awe on men, and engage them to a watchfulness over their thoughts, words, and actions.
