'Stumbling blocks' in the Bible

For this, thus said Jehovah, Behold me giving to this people stumbling blocks, and they stumbled upon them, the fathers and sons together; the inhabitant and his neighbor shall perish

I will take away man and cattle; I will take away the birds of the heavens, and the fish of the sea, and the stumbling blocks with. the unjust; and I cut off man from the face of the earth, says Jehovah.
