'Apple tree' in the Bible

As the apple tree among the trees of the wood, so is my beloved among the sons. I sat down under his shadow with great delight, and his fruit was sweet to my taste.

Who is this that comes up from the wilderness, leaning upon her beloved? I awakened you under the apple tree: there your mother brought you forth: there she brought you forth that bore you.

The vine is dried up, and the fig tree languishes; the pomegranate tree, the palm tree also, and the apple tree, even all the trees of the field, are withered: because joy has withered away from the sons of men.
