Albert Barnes Commentary Luke 1:67

"And his father Zacharias was filled with the Holy Spirit, and prophesied, saying," — Luke 1:67 (ASV)

Filled with the Holy Ghost. See Luke 1:15.

And prophesied. The word prophesy means —

1. To foretell future events.
2. To celebrate the praises of God (see 1 Samuel 10:5–6; 1 Kings 18:29); then to
3. Teach or preach the gospel, etc. (see Barnes on "Romans 12:6").

This song of Zacharias partakes of all. It is principally employed in the praises of God, but it also predicts the future character and preaching of John.
