'Apple' in the Bible

Keep my commandments and live,And keep my teaching and law as the apple of your eye.

(The Shulammite Bride)“Like an apple tree [rare and welcome] among the trees of the forest,So is my beloved among the young men!In his shade I took great delight and sat down,And his fruit was sweet and delicious to my palate.

(The Chorus)“Who is this coming up from the wildernessLeaning upon her beloved?”

The vine dries upAnd the fig tree fails;The pomegranate, the palm also, and the apple tree,All the trees of the field dry up,Indeed, joy dries up and withdrawsFrom the sons of men.

For thus says the Lord of hosts, “After glory He has sent Me against the nations which plunder you—for he who touches you, touches the apple of His eye.
