John Gill Commentary Ezekiel 34:30

"And they shall know that I, Jehovah, their God am with them, and that they, the house of Israel, are my people, saith the Lord Jehovah." — Ezekiel 34:30 (ASV)

Thus shall they know that I the Lord their God am with them , &c.] Granting them his gracious and powerful presence, by all the above instances of his goodness and favour to them: and that they, even the house of Israel, are my people, says the Lord God : and not utterly cast off, as they seemed to be; the divine Shechinah now being returned to them, which had departed from them; the "loammi" that was written on them being now wiped off from them.
