Adam Clarke on Jeremiah 28:1

And it came to pass the same year - the fifth month - Which commenced with the first new moon of August, according to our calendar. This verse gives the precise date of the prophecy in the preceding chapter; and proves that Zedekiah, not Jehoiakim, is the name that should be read in the first verse of that chapter.

Hananiah the son of Azur the prophet - One who called himself a prophet; who pretended to be in commerce with the Lord, and to receive revelations from him. He was probably a priest; for he was of Gibeon, a sacerdotal city in the tribe of Benjamin.
