a Bible passage
9Esau went to Ishmael and took Mahalath daughter of Abraham’s son Ishmael, and sister of Nebaioth, to be his wife in addition to the wives he had.
Good examples impress even the profane and malicious. But Esau thought, by pleasing his parents in one thing, to atone for other wrong doings. Carnal hearts are apt to think themselves as good as they should be, because in some one matter they are not so bad as they have been.
