'Slippery' in the Bible

Let their way be dark and slippery: and let the angel of the LORD persecute them.

Surely thou didst set them in slippery places: thou castedst them down into destruction.

Wherefore their way shall be unto them as slippery ways in the darkness: they shall be driven on, and fall therein: for I will bring evil upon them, even the year of their visitation, saith the LORD.
