6 "Then, after you have done this, turn over and lie down on your right side and bear the sin of the family of Judah. Your assignment this time is to lie there for forty days, a day for each year of their sin.

Matthew Henry's Commentary on Ezekiel 4:6

Commentary on Ezekiel 4:1-8

(Read Ezekiel 4:1-8)

The prophet was to represent the siege of Jerusalem by signs. He was to lie on his left side for a number of days, supposed to be equal to the years from the establishment of idolatry. All that the prophet sets before the children of his people, about the destruction of Jerusalem, is to show that sin is the provoking cause of the ruin of that once flourishing city.
