Ezekiel 4:5

This verse explains the former. I have pointed out the number of years wherein apostate Israel sinned against me, and I did bear with them according to the number of days, wherein thou must lie on thy left side. Three hundred and ninety days. See Ezekiel 4:4. There is some difference, though of no great moment, in fixing the periods of beginning and ending these prophetic days. These years some begin at Solomon's falling to idolatry, in the twenty-seventh year of his reign, and end them in the fifth of Zedekiah's captivity. Others begin at the fourth year of Rehoboam, and end them in the twenty-first year of the captivity. Others begin them in the first of Rehoboam and Jeroboam, when the kingdom was divided, and then they must end about the seventeenth year of the captivity. The first supputation to me is much the likeliest, and agrees nearest with the year wherein this prophet begins his prophecy. It is not altogether unlikely that the prophet may intimate, though obscurely, the continuance of the siege of Jerusalem, which the Chaldeans began on the tenth day of the tenth month of the ninth year of Zedekiah, and lasted the remaining two months of the ninth year, and the whole tenth year except some five months, wherein the Babylonians retired to fight the Egyptians, beat them, spoiled them, and returned to the siege of Jerusalem, which lasted to the ninth day of the fourth month of Zedekiah's eleventh year. So that one whole year, and three weeks, and four days, or thirteen months, at thirty days in each month, taking up three hundred and ninety days, and discounting the five months and odd days in the Egyptian expedition, you come to the continuance of three hundred and ninety days in the threatened siege, and possibly this may be the intent of the prophecy.
