'Stumbling Block' in the Bible

You shall not curse the deaf, nor put a stumbling block before the blind, but shall fear your God: I am the LORD.

And it shall be said, Heap it up, heap it up, prepare the way, take up the stumbling block out of the way of my people.

I will consume man and beast; I will consume the fowls of the heaven, and the fish of the sea, and the stumbling blocks with the wicked; and I will cut off man from off the land, says the LORD.
