was customary among the Jews (Lightfoot, Horae Hebr. on Matthew 20:36), and forms are contained in the Talmud (Berachoth, 7).

Paedag. 2:4, 44, 77; so also Tertullian, Cyprian, and others). Examples of forms occur both in the early Eastern and Western churches, and the Gelasian Sacramentary sets forth quite a number.
