'Leafy' in the Bible

Be sure you destroy there all the places where the nations that you're going to dispossess serve their gods upon the high mountains and hills and under every leafy tree.

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.
