If he; either God, who is the Saviour of good men, and the Destroyer of the wicked; or the owner; or any other man; for this is an indefinite speech, and may be taken passively and impersonally; which is very common in the holy text and language. From his place, in which he was planted. Then it, i.e. the place; to which denying him and seeing him are here ascribed figuratively, as we have oft seen. I have not seen thee, i.e. I do not know nor remember that ever thou wast planted here. He shall be so utterly extirpated and destroyed, that there shall be no footstep, nor name, nor memorial of him left there.
