Lie thou also upon thy left side, and lay the iniquity of the house of Israel upon it: according to the number of the days that thou shalt lie upon it thou shalt bear their iniquity.
Lie thou also upon thy left side - another symbolical act, performed at the same time as the former, in vision, not in external action, wherein it would have been only puerile: narrated as a thing ideally done, it would make a vivid impression. The second action is supplementary to the first, to bring out more fully the same prophetic idea.
Left side - referring to the position of the ten tribes, the Northern Kingdom; as Judah, the Southern, answers to "the right side" (Ezekiel 4:6). The Orientals, facing the East in their mode, had the North on their left and the South on their right (Ezekiel 16:46). Also, the right was more honourable than the left; so Judah, as being the seat of the temple, was more so than Israel.
According to the number of the days that thou shalt lie upon it, thou shalt bear their iniquity - iniquity being regarded as a burden; so it means, "bear the punishment of their iniquity" (Numbers 14:34). A type of Him who was the great sin-bearer, not in mimic show, as Ezekiel, but in reality (Isaiah 53:4; Isaiah 53:6; Isaiah 53:12).
