'Slippery' in the Bible

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

Surely You set the wicked-minded and immoral on slippery places;You cast them down to destruction.

“Therefore their way will be to them like slippery pathsIn the dark; they will be pushed and fall into them;For I will bring disaster on them,In the year of their punishment,” says the Lord.
