Turtle-doves and young pigeons were allowed for sacrifices (Lev. 1: 14; Luke 2: 24). Wild birds were hunted (Amos 3: 5; Ps. 91: 3). The migratory habits of birds were well known (Jer. 8: 7), and quails migrating from Africa to Europe fed the Israelites in the wilderness (Exod. 16: 13). Birds regarded as unclean are listed in Lev. 11: 13–19, together with bats. Birds are mentioned in the gospels as not having much financial value (Luke 12: 6–7, 24), yet are significant to God (Matt. 6: 26; 8: 20).
