'As I Live' in the Bible

So why do you criticize your brother? And you, why do you look down upon your brother? All of us have to stand before the tribunal of God ??11 for it is written, As I live, saith the Lord, every knee shall bend before me, every tongue shall offer praise to God.

Therefore if food is any hindrance to my brother's welfare, sooner than injure him I will never eat flesh as long as I live, never!
