'Foliage' 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.

"Tell them, "This is what the Lord GOD says, "Will it prosper? Won't he pull up its roots, and strip it bare so all its fresh foliage dries up? It won't be by great strength or by a great army that it will be uprooted.
