'Stumbling blocks' in the Bible

Therefore thus says LORD: Behold, I will lay stumbling-blocks before this people, and the fathers and the sons together shall stumble against them. The neighbor and his friend shall perish.

I will consume man and beast. I will consume the birds of the heavens, and the fishes of the sea, and the stumbling blocks with the wicked. And I will cut off man from off the face of the ground, says LORD.

The Son of man will send forth his agents, and they will gather out of his kingdom all the stumbling-blocks, and those doing lawlessness,

Woe to the world because of stumbling-blocks. For it is necessary that the stumbling-blocks come, yet woe to that man through whom the stumbling-block comes.

And he said to his disciples, It is impossible for the stumbling-blocks not to come, but woe to him through whom they come!

Now I beseech you, brothers, watch out for those who make the divisions and the stumbling blocks, contrary to the doctrine that ye learned, and turn away from them.
