'Leafy' in the Bible

Then you will know that I am the Lord -- when their dead lie among their idols around their altars, on every high hill and all the mountaintops, under every green tree and every leafy oak, the places where they have offered fragrant incense to all their idols.

I brought them to the land which I swore to give them, but whenever they saw any high hill or leafy tree, they offered their sacrifices there and presented the offerings that provoke me to anger. They offered their soothing aroma there and poured out their drink offerings.
