Nevertheless the son of Pharaoh did not give up his criminal purpose. He approached the sons of Bilhah and Zilpah, and sought to accomplish through them what had failed with Simon and Levi. He called them into his presence, and told them of a conversation between Joseph and Pharaoh that he had overheard. The former had said that he waited but to learn of the death of his father Jacob in order to do away with the sons of the handmaids, because they had been the ones to sell him into slavery.

Their wrath excited against Joseph by these words, the sons of Bilhah and Zilpah assented to the proposition of the son of Pharaoh. It was arranged that the latter should kill Pharaoh, the friend of Joseph, while they would fall upon their brother, and put him out of the way. They were furnished with six hundred able warriors and fifty spearmen for the purpose. The first part of the plan, the murder of Pharaoh, failed.

The palace guard would not allow even the successor to the throne to enter his father's bedchamber, and he had to depart without having effected his object.
