Matthew Poole and continuators on Job 8:18

18. If he destroy him from his place , then it shall deny him, saying, I have not seen thee .

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.

In which he was planted.

i. e. The place; to which denying him, and seeing him, are here ascribed figuratively, as we have oft seen.

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 them left there.
