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 will say to him, For what will my lord speak according to these words? far be it for thy servants to do according to this word.
And he will say, Far be it for me to do this: the man in whose band the cup being found, he shall be servant to me; and ye, go ye up in peace to your father.
It may not be: and let God be true, and every man a liar; as has been written, That thou mightest be justified in thy words, and mightest conquer in thy being judged.
