'Slippery' in the Bible

Let their way be dark and slippery, and let the angel of Jehovah pursue them.

Truly thou settest them in slippery places, thou castest them down in ruins.

Therefore their way shall be unto them as slippery places in the darkness; they shall be driven on, and fall therein: for I will bring evil upon them in the year of their visitation, saith Jehovah.
