GEN1244 The most famous lie told in the Torah (Jacob telling his blind father, Isaac, that he was Esau, Isaac’s firstborn son) came about because of Rebecca’s fear that her son Jacob, and all his descendants, would suffer unfairly if he did not lie to his father. … This instance is a difficult case, one that pushes the border between permissible and impermissible lies.   Nonetheless, it would appear that the Bible is teaching that one may lie when an injustice, in this case a major injustice, will occur if one doesn’t.
