We’ve seen that He affirms that she has eyes like doves behind her veil, which means that she is a true lover of God even though it isn’t always obvious in her behavior. He affirms her longings to love Him with all of her heart, and her inconsistent expressions of obedience, as genuine love.
There is also an alternative meaning to this expression, “your eyes are like doves behind your veil.” The veil can represent that which divides life in the secret place from practical life lived out in the world. When you spend enough time behind the veil, in the secret place with Jesus, you develop doves eyes. As I’m sure you are aware, doves are one of the types of the Holy Spirit, and He is saying to her that she, having spent more time alone with him behind the veil, is beginning to see things with the eyes of the Holy Spirit. When you develop doves eyes it becomes much easier to see things as God sees them, and to discern God’s will in each situation and circumstance of life. As the Son of Man, Jesus spent so much time alone with his Father that He developed doves eyes to such a degree that He could say that He only did those things He saw the Father doing. Her decision to pursue Him in love, as the quest of her life has so pushed her to spend more time behind the veil that He sees doves eyes being developed in her. It’s part of her emerging beauty tha Het is so enthralled with.
