[45] When, therefore, there was a public festival coming on, in which it was the custom for women to come to the public solemnity; she pretended to her husband that she was sick, as contriving an opportunity for solitude and leisure, that she might entreat Joseph again. Which opportunity being obtained, she used more kind words to him than before; and said that it had been good for him to have yielded to her first solicitation, and to have given her no repulse, both because of the reverence he ought to bear to her dignity who solicited him, and because of the vehemence of her passion, by which she was forced though she were his mistress to condescend beneath her dignity; but that he may now, by taking more prudent advice, wipe off the imputation of his former folly; for whether it were that he expected the repetition of her solicitations she had now made, and that with greater earnestness than before, for that she had pretended sickness on this very account, and had preferred his conversation before the festival and its solemnity; or whether he opposed her former discourses, as not believing she could be in earnest; she now gave him sufficient security, by thus repeating her application, that she meant not in the least by fraud to impose upon him; and assured him, that if he complied with her affections, he might expect the enjoyment of the advantages he already had; and if he were submissive to her, he should have still greater advantages; but that he must look for revenge and hatred from her, in case he rejected her desires, and preferred the reputation of chastity before his mistress; for that he would gain nothing by such procedure, because she would then become his accuser, and would falsely pretend to her husband, that he had attempted her chastity; and that Potiphar would hearken to her words rather than to his, let his be ever so agreeable to the truth.
