Kings IV 10:23 In-Context

21 And Ju sent throughout all Israel, saying, Now then let all servants, and all his priests, and all his prophets , let none be lacking: for I am going to offer a great sacrifice; whosoever shall be missing, shall not live. So all the servants of Baal came, and all his priests, and all his prophets: there was not one left who came not. And they entered into the house of Baal; and the house of Baal was filled from one end to the other.
22 And he said to the man who was over the house of the wardrobe, Bring forth a robe for all the servants of Baal. And the keeper of the robes brought forth to them.
23 And Ju and Jonadab the son of Rechab entered into the house of Baal, and said to the servants of Baal, Search, and see whether there is among you any of the servants of the Lord, or only the servants of Baal, by themselves.
24 And he went in to offer sacrifices and whole-burnt-offerings; and Ju set for himself eighty men without, and said, Every man who shall escape of the men whom I bring into your hand, the life of him shall go for his life.
25 And it came to pass, when he had finished offering the whole-burnt-offering, that Ju said to the footmen and to the officers, Go ye in and slay them; let not a man of them escape. So they smote them with the edge of the sword, and the footmen and the officers cast forth, and went to the city of the house of Baal.
