Robertson's Word Pictures (NT)
They are together become unprofitable (ama hxrewqhsan). First aorist passive indicative of axreow. Late word in Polybius and Cilician inscription of first century AD Some MSS. read hxreiwqhsan from axreiov, useless (a privative and xreiov, useful) as in Luke 17:10; Matthew 25:30, but Westcott and Hort print as above from the rarer spelling axreov. Only here in N.T. The Hebrew word means to go bad, become sour like milk (Lightfoot).
No, not so much as one (ouk estin ewv enov). "There is not up to one."
