'Doves' in the Bible

Behold, thou art fair, my love; Behold thou art fair; Thine eyes are as doves.

Behold, thou art fair, my love; behold, thou art fair; Thine eyes are as doves behind thy veil. Thy hair is as a flock of goats, That lie along the side of mount Gilead.

His eyes are like doves beside the water-brooks, Washed with milk, and fitly set.
