'Slippery' in the Bible

Only, in slippery places Thou dost set them, Thou hast caused them to fall to desolations.

Therefore is their way to them as slippery places, Into thick darkness they are driven, And they have fallen in it, For I bring in against them evil, The year of their inspection, An affirmation of Jehovah.

Gilead is a city of workers of iniquity, Slippery from blood.
