And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision. ~ Galatians 2:9 KJV

And when they knew (perceived, recognized, understood, and acknowledged) the grace (God’s unmerited favor and spiritual blessing) that had been bestowed upon me, James and Cephas (Peter) and John, who were reputed to be pillars of the Jerusalem church, gave to me and Barnabas the right hand of fellowship, with the understanding that we should go to the Gentiles and they to the circumcised (Jews). ~ Galatians 2:9 AMP
