'Hill' in the Bible

"You'll learn that I am the LORD, when the fatally wounded will be among their idols, around their altars, on every hill, on top of the mountains, under every luxuriant tree, and under all the full-grown foliage every place where they've offered fragrant aromas to all their idols.

I brought them to the land that I had promised to give them. But whenever they saw any high hill and or any leafy tree, they slaughtered their sacrifices there and presented their offerings that provoked my anger. There they presented their pleasing aromas and poured out their drink offering.

I'm going to make them and everything that surrounds my hill a blessing. I'll send down the rain! At the appropriate time there will be a rainstorm of blessing!
