Targum su Deuteronomio 32:33

Behold as the bitterness of serpents when they come forth from their wines, (?) so shall be the bitter cup of the curse which they are to drink in the day of their punishment, and cruel as the head of asps.

For the poison of this people is like that of serpents what time they drink wine, and their malice like the head of asps and cruel reptiles.
