Deuteronomy 32:33 Meaning

31For their rock is not as our Rock, even our enemies themselves being judges.

32For their vine is of the vine of Sodom, and of the fields of Gomorrah: their grapes are grapes of gall, their clusters are bitter:

33Their wine is the poison of dragons, and the cruel venom of asps.

34Is not this laid up in store with me, and sealed up among my treasures?

35To me belongeth vengeance, and recompence; their foot shall slide in due time: for the day of their calamity is at hand, and the things that shall come upon them make haste.
