'Doves' in the Bible

Behold, thou art fair, my love; behold, thou art fair; thou hast doves' eyes.

Behold, thou art fair, my love; behold, thou art fair; thou hast doves' eyes within thy locks: thy hair is as a flock of goats, that appear from mount Gilead.

His eyes are as the eyes of doves by the rivers of waters, washed with milk, and fitly set.
