'Ravines' in the Bible

All of them will come and settlein the steep ravines, in the clefts of the rocks,in all the thornbushes, and in all the water holes.

you who burn with lust among the oaks, under every spreading tree, who slaughter your children in the ravines, under the clefts of the rocks?

"Among the smooth stones of the ravines is your portion there they are as your lot. To them you have poured out drink offerings; you have brought grain offerings. Should I be lenient over such things?
