Isaiah 57:5-7

5You worship your idols among the big trees, and you have sex at the same time. You kill your children as sacrifices to your false gods. You do that beside streams and in caves among the rocks.

6You take big stones from the streams, and they become your idols. They are the gods that you love to worship. You pour drink offerings over them. You offer grain to them. Because of what you do, should I not punish you?

7You go up to the tops of high hills, and you lie down there to have sex. You go there to offer sacrifices to your gods.
