means unprofitable. It is used twice in the New Testament, both times in a moral sense. The first instance is this: “But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain” (Tit. 3:9). Stupid wrangles sown produce a harvest to match. The second usage does not refer to sin, but does refer to the inability of the older covenant to put us right with God once for all. In that sense it was unprofitable (Heb. 7:18).
