Romans 9:32 Why? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumbling-stone; (WBS)
Romans 9:33 As it is written, Behold, I lay in Sion a stumbling-stone, and rock of offense: and whoever believeth on him shall not be ashamed. (WBS)
Romans 14:13 no longer, therefore, may we judge one another, but this judge ye rather, not to put a stumbling-stone before the brother, or an offence. (YLT)
