the turtledove: a small migratory dove, named in Hebrew for its soft rolling coo
Hebrew named this bird by its sound. The word imitates the soft, rolling coo of the turtledove, in the same way that English "turtledove", Latin "turtur" and German "Turteltaube" all echo the same call. It is a name built out of listening, and it has nothing to do with the identically spelled Hebrew words for scouting out a land (תּוּר) or for a turn in a sequence (תּוֹר).
The bird is a spring visitor. It winters in Africa and returns to the hills of Israel on so reliable a schedule that its voice worked as a calendar. Two of the best known uses turn on exactly that punctuality: the love poem hears the dove and knows the winter is over (Song of Songs 2:12), and the prophet holds the bird up as a creature that keeps its appointed time while God's own people do not (Jeremiah 8:7).
Every other appearance is a sacrifice. Most come from the law, where the bird is paired with the pigeon (יוֹנָה) in a set phrase, "two turtledoves or two young pigeons", and it is always what a worshipper brings who cannot afford anything larger:
- a burnt offering for someone who cannot bring a bull or a sheep (Leviticus 1:14)
- two birds in place of a lamb when a person owes a sin offering (Leviticus 5:7)
- the cheaper option for a mother after childbirth (Leviticus 12:8)
- the closing rites for a healed skin disease and for a bodily discharge (Leviticus 14:22, Leviticus 15:14)
- a fresh start for a Nazirite whose vow was broken by a death nearby (Numbers 6:10)
The oldest appearance is different in kind: a turtledove is among the animals Abram sets out when God makes his covenant with him (Genesis 15:9). And that mix of the cheap and the sacred is what makes the bird useful as a picture. When one psalm begs God not to hand his suffering people over to wild animals, it calls them his turtledove (Psalm 74:19): small, defenseless, and worth almost nothing to anyone but the one who owns it.
