'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 who comes up from the wilderness, leaning upon her beloved? Under the apple tree I awoke thee. There thy mother was in travail with thee. There she who brought thee forth was in travail.

The vine is withered, 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. For joy has withered away from the sons of men.
