Albert Barnes on Acts 13:32

And we. We who are present. Paul and Barnabas.

Declare unto you glad tidings We preach the gospel--the good news. To a Jew, nothing could be more grateful intelligence than that the Messiah had come; to a sinner convinced of his sins, nothing can be more cheering than to hear of a Saviour.

The promises, etc. The promise here refers to all that had been spoken in the Old Testament respecting the advent, sufferings, death, and resurrection of Christ.

(a) "promise" Rom 4:13
