Waxed bold. See Acts 9:27, 29; 13:9-11.
First ... to you. Christ came first to His own (John 1:11), so His messengers declared good news first to Jews. Gospel preaching order was “to the Jew first, and also to the Gentile” (Rom. 2:10). Preaching to Jews aimed for their becoming means by which “all nations” would be blessed (Gen. 22:18). They rejected this privilege, so the message went to Gentiles.
Unworthy. Paul’s words have irony. Jews thought themselves worthy of God’s highest blessings; apostles brought them eternal life through Christ. But their exclusiveness and pride led to rejection, showing themselves “unworthy.” Their refusal passed judgment on themselves.
To the Gentiles. Echoes Paul’s vision in the Jerusalem Temple after conversion (Acts 22:21). Believing Gentiles heard with joy; Jews with envy.
