'Slippery' in the Bible

Let their way be dark and slippery,with the angel of the Lord pursuing them.

Indeed, You put them in slippery places;You make them fall into ruin.

Therefore, their way will be to themlike slippery paths in the gloom.They will be driven away and fall down there,for I will bring disaster on them,the year of their punishment.This is the Lord’s declaration.
