Nehemiah 6:3 - Joseph Benson’s Commentary on the Old and New Testaments

I am doing a great work He acquainted them that he thought the business which they might have with him could not be of such importance as that which he had in hand; and therefore he would not put a stop to it to come and confer with them. Thus he tells them one, but not the only, nor the principal reason of his refusal; for he properly judged that it would answer no good end to intimate to them his suspicions of their design to compass his death.
