'Fall' in the Bible

As it is said, See, I am putting in Zion a stone causing a fall, and a rock in the way: but he who has faith in him will not be put to shame.

So I say, Were their steps made hard in order that they might have a fall? In no way: but by their fall salvation has come to the Gentiles, so that they might be moved to envy.

Now, if their fall is the wealth of the world, and their loss the wealth of the Gentiles, how much greater will be the glory when they are made full?
