Isaiah 53:2 - Wesley's Explanatory Notes

As a root — And the reason why the Jews will generally reject their Messiah, is, because he shall not come into the world with secular pomp, but he shall grow up, (or spring up, out of the ground) before him, (before the unbelieving Jews, of whom he spake Isaiah 53:1, and that in the singular number, as here, who were witnesses of his mean original; and therefore despised him) as a tender plant (small and inconsiderable) and as a root, or branch, grows out of a dry, barren ground. No form — His bodily presence shall be mean and contemptible. No beauty — This the prophet speaks in the person of the unbelieving Jews. We — Our people, the Jewish nation.
