ἀββα

Abba = &quot-father&quot-, father, customary title used of God in prayer. Whenever it occurs in the New Testament it has the Greek interpretation joined to it, that is apparently to be explained by the fact that the Chaldee &quot-ABBA&quot- through frequent use in prayer, gradually acquired the nature of a most sacred proper name, to which the Greek speaking Jews added the name from their own tongue.
