ISB ~ Galatians 1 v18

after three years:Corresponds to the “many days” that passed before Paul was forced to flee Damascus (Acts 9:2325). It was then that he traveled to Jerusalem for the first time as a Christian (Acts 9:26-29).

to visit:The Greek expression is more precise, indicating that Paul “interviewed” Peter, as well as “made his acquaintance”. He must have spent these two weeks gathering information about the life and ministry of Jesus.

Cephas:Another name for Simon Peter, often used in Paul’s letters (2:9, 11; 1 Cor 1:12; 9:5; 15:5). It transliterates an Aramaic word meaning “rock”.

See word study:Peter at Mt 16:18.
