Deuteronomy 32:32 - Joseph Benson’s Commentary on the Old and New Testaments

Their vine is the vine of Sodom God had planted Israel a noble vine, a right seed, but they turned into the degenerate plant of a strange vine, Jeremiah 2:21. Their principles and practices became corrupt and abominable. Their grapes are grapes of gall Their fruits are loathsome to me, mischievous to others, and at last will be pernicious to themselves. And so Josephus, their own countryman, describes them before their last destruction, when he says, their city was so wicked that, if the Romans had not fallen upon them, the earth would have opened its mouth and swallowed them up, or thunder and lightning from heaven must have destroyed them as it did Sodom: for “they were a more atheistical nation than those who suffered such things.” And in another place, that “there was no one work of wickedness that was not committed, nor can one imagine any thing so bad that they did not do; endeavouring publicly, as well as privately, to exceed one another, both in impiety toward God, and injustice to their neighbours.”
