And Jehu went, and Jehonadab the son of Rechab, into the house of Baal, and said unto the worshippers of Baal, Search, and look that there be here with you none of the servants of the LORD, but the worshippers of Baal only. None of the servants of the Lord - Though he was not attached to that service, yet he would tolerate it; and as he was led to suppose that he was fulfilling the will of Jehovah in what he was doing, he would of course treat his worship and worshippers with the more respect.
He might have ordered the search to be made on pretense of expelling any of those whom they would consider the profane, especially as this was "a solemn assembly for Baal," as was the custom with the heathen when any extraordinary exhibition of or for their god was expected; thus Callimachus, (Hymn to Apollo), after imagining the temple and its suburbs to be shaken by the approach of Apollo, cries out, Εκας, ἑκας, ὁστις, αλιτρος. To prevent any suspicion of his real design, such might have been Jehu's plea, else alarm must have been excited, and perhaps some would have escaped.
