Thematic Bible: Jehu lied to the worshipers of baal in order to gain the advantage over them and destroy them

Then Jehu got all the people together and said to them, Ahab was Baal's servant in a small way, but Jehu will be his servant on a great scale. Now send for all the prophets of Baal and all his servants and all his priests, to come to me; let no one keep away: for I have a great offering to make to Baal; anyone who is not present, will be put to death. This Jehu did with deceit, his purpose being the destruction of the servants of Baal. And Jehu said, Let there be a special holy meeting for the worship of Baal. So a public statement was made. read more.
And Jehu sent out through all Israel; and all the servants of Baal came, not one kept away. And they came into the house of Baal, so that it was full from end to end. And Jehu said to him who kept the robes, Get out robes for all the servants of Baal. So he got out robes for them. And Jehu, with Jehonadab, the son of Rechab, went into the house of Baal; and he said to the servants of Baal, Make a search with care, to see that no servant of the Lord is with you, but only servants of Baal. Then they went in to make offerings and burned offerings. Now Jehu had put eighty men outside, and said to them, If any man whom I give into your hands gets away, the life of him who lets him go will be the price of his life. Then when the burned offering was ended, straight away Jehu said to the armed men and the captains, Go in and put them to death; let not one come out. So they put them to the sword; and, pulling the images to the earth, they went into the holy place of the house of Baal. And they took out the image of Asherah from the house of Baal, and had it burned. The altar of Baal was pulled down and the house of Baal was broken up and made an unclean place, as it is to this day. So Jehu put an end to the worship of Baal in Israel.
