As usual, Ezekiel mentioned an exact date. This was the 10th day, of the 10th month, of the 9th year of the reign of King Zedekiah. This seems to be January 15, 588 BCE. Once again, Yahweh appeared to Ezekiel, the son of man, who was still probably in Babylon. Yahweh wanted him to write this exact date down because it was the day that Babylon began its siege of Jerusalem.
Once again, this is an exact date, word for word as in 2 Kings, chapter 25 and earlier in this book of Jeremiah, in chapter 39. It is rare that we have exact dating, but here it is very specific, not some vague “at that time.” In the 9th year of King Zedekiah, in the 10th month on the 10th day, King Nebuchadnezzar of Babylon came with his army to Jerusalem in order to besiege the city. King Zedekiah had probably began to plot with the Egyptians and rebelled against the king of Babylon. This siege of Jerusalem began in 588 BCE and lasted about 18 months to 2 years
