[There is] none greater in this house than I,.... Not any of the servants of the house, he was the chief of them, who had all the rest under him; or rather, "he himself is not greater q in this house than I"; that is, his master was not greater than he: he had a greater propriety in the house and the things of it, and he had the original power and authority in it, but had not a greater use of it; Joseph had authority over all the servants, and everything in the house at his command, and the free use of everything his master had, excepting what follows:
neither hath he kept back anything from me but thee, because thou [art] his wife; and is a reason not only why his master retained her for his own use, but why he should not touch her, and why she should not solicit him to it:
how then can I do this great wickedness and sin against God? the words are emphatic in the original, "this! this wickedness! this great one!" adultery was reckoned a great sin among all nations, and this, had Joseph committed it, would have been greatly aggravated by the favours his master had conferred upon him; and not only a sin against himself, his soul and body, and against his master, but, above all, a sin against God, contrary to his holy nature, revealed will, and righteous law; all which prevailed upon Joseph to refuse the offer made him, which he could not comply with, in honour or with a good conscience.
