Then Moses said, “Behold, I am going out from you, and I shall make supplication to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people tomorrow; only do not let Pharaoh deal deceitfully again in not letting the people go to sacrifice to the Lord.”

He sent messengers to Abimelech deceitfully, saying, “Behold, Gaal the son of Ebed and his relatives have come to Shechem; and behold, they are stirring up the city against you.

“My brothers have acted deceitfully like a wadi,Like the torrents of wadis which vanish,

He who has clean hands and a pure heart,Who has not lifted up his soul to falsehoodAnd has not sworn deceitfully.

Let death come deceitfully upon them;Let them go down alive to Sheol,For evil is in their dwelling, in their midst.
