Galatians 1:24

24 When the believers in Judea heard that, they praised God because of me.

1:18Peter was one of Jesus' 12 apostles.
1:21Syria and Cilicia were places north of Israel, south-east of Galatia, near to the Mediterranean Sea.
1:22Judea was the south region of Israel. Jerusalem, the capital city of Israel, was in Judea.
