Job 8:18

“If he destroy him from his place, etc.] If the sun when he is risen strikes the tree with such vehement heat that it withers and utterly perishes from the place where it grew; or roots it up, so the Targum and Nachmanides; or, if God destroys the hypocrite from his place, or he is by one means or another removed out of the garden, the church, being detested and rejected by good men; or from all his worldly enjoyments, his honour, credit, and esteem with men, which are all precarious, fickle, and inconstant; or out of the world, being cut down as a cumber ground: then [it] shall deny him, [saying], I have not seen thee; that is, either the tree shall deny that it ever was planted in such a…”
