But if any man say unto you (ean de ti umin eiph). Condition of third class. Suppose at such a banquet a "weak" brother makes the point to you: "This hath been offered in sacrifice" (touto ieroquton estin). Hieroquton, late word in Plutarch, rare in inscriptions and papyri, only here in N.T. Eat not (mh esqiete). Present imperative with mh prohibiting the habit of eating then. Pertinent illustration to the point of doing what is expedient and edifying. That shewed it (ton mhnusanta). First aorist active articular participle (accusative case because of dia) from mhnuw, old verb, to point out, to disclose. See Luke 20:37 .
