Albert Barnes Commentary Acts 13:26

"Brethren, children of the stock of Abraham, and those among you that fear God, to us is the word of this salvation sent forth." — Acts 13:26 (ASV)

Men and brethren. Paul now exhorts them to embrace the Lord Jesus as the Messiah. He uses, therefore, the most respectful and fraternal language.

Children of the stock of Abraham. Descendants of Abraham, who regard Abraham as their ancestor. He means here to address particularly the native-born Jews. This term is used because they valued themselves highly on account of their descent from Abraham (see Barnes on Matthew 3:9) and because the promise of the Messiah had been specially given to him.

And whosoever, etc. This refers to proselytes (see Barnes on Acts 13:16).

Is the word of this salvation sent. This refers to this message of salvation. It was sent particularly to the Jewish people. The Saviour was sent to that nation (Matthew 15:24), and the design was to offer to them first the message of life (see Barnes on Acts 13:46).
