Jeremiah 28:9

Matthew Henry on Jeremiah 28:1-9

This struggle between a true prophet and a false one is said here to have happened in the beginning of the reign of Zedekiah, and yet in the fourth year, for the first four years of his reign might well be called the beginning, or former part, of it, because during those years he reigned under the dominion of the king of Babylon and as a tributary to him; whereas the rest of his reign, which might well be called the latter part of it, in distinction from that former part, he reigned in rebellion against the king of Babylon.
