'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, his fruit was sweet to my taste.

Who is this who comes up from the wilderness, leaning on her beloved? Under the apple tree I aroused you. There your mother conceived you. There she was in labor and bore you.

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