'A turtle dove,' as in Psalms 74:19, signifies spiritual good.

In Genesis 15:9, this signifies spiritual things belonging to faith or to truth: The turtle-dove signifies exterior spiritual things, and a young pigeon interior. (Arcana Coelestia 1826, 1827)

In Leviticus 12:6, turtle doves signify the effect of marriage love, or the good of innocence. (Arcana Coelestia 3394)
