This is an unhappy expression, bringing in the name of God where it does not occur. In the O.T. it is chalilah, 'far be it.' Ge 44:7,17, etc. In the N.T. ?? ???????, 'let it not be.' Ro 3:4,6,31, etc.
And they said to him, Why does my lord speak such words as these? Far be it from thy servants that they should do such a thing.
And he said, Far be it from me that I should do so. The man in whose hand the cup is found, he shall be my bondman, but as for you, get you up in peace to your father.
May it not happen! But let it come to pass God is true, but every man a liar, as it is written, That thou may ever be justified in thy words, and may prevail when thou are criticized.
May it not happen! Otherwise how will God judge the world?
Do we then make law void through faith? May it not happen! Instead, we establish law.
