Targum su Genesi 49:23

And all the magicians of Mizraim were bitter and angry against him, and brought accusations against him before Pharoh, expecting to bring him down from his honour They spake against him with the slanderous tongue which is severe as arrows.

The magicians of Mizraim and all the wise men spake against him, but could not prevail over him; they spake evil of him before his lord, they accused him before Pharoh king of Mizraim, to bring him down from his dignity; they spake against him in the palace of Pharoh with a slanderous tongue severe as arrows.
