'High places' in the Bible

They have built high places at Topheth in the Valley of Ben-hinnom to burn their sons and daughters in the fire. I didn't command this, and it never entered my mind!

My mountain in the field, your wealth and your treasures I'll give as spoil; along with your high places as the price of your sin throughout your territory.

They built the high places for Baal to burn their children in the fire as a burnt offering to Baal something I didn't command, didn't say, nor did it ever enter my mind!

They built the high places of Baal that are in the Hinnom Valley in order to sacrifice their sons and daughters to Molech something that I didn't command, nor did it ever enter my mind for them to require this utterly repugnant thing and lead Judah into sin."
