'Apple tree' in the Bible

As the apple-tree among the trees of the wood, so is my loved one among the sons. I took my rest under his shade with great delight, and his fruit was sweet to my taste.

Who is this, who comes up from the waste places, resting on her loved one? It was I who made you awake under the apple-tree, where your mother gave you birth; there she was in pain at your birth.

The vine has become dry and the fig-tree is feeble; the pomegranate and the palm-tree and the apple-tree, even all the trees of the field, are dry: because joy has gone from the sons of men.
