Prophesied (eprophteusen). Under the guidance of the Holy Spirit. This Benedictus (Euloghto, Blessed) of Zacharias ( Acts 68-79 ) may be what is referred to in verse Acts 64 "he began to speak blessing God" (eulogwn). Nearly every phrase here is found in the O.T. (Psalms and Prophets). He, like Mary, was full of the Holy Spirit and had caught the Messianic message in its highest meaning.
