'Apostles and Elders' in the Bible

[It was] in response to [a divine] revelation that I went [there] and explained to them [I. e., the apostles and elders] the Gospel [message] that I had been preaching among the Gentiles. Then [later on I presented it] privately before those who were highly regarded [i.e., the three apostles, verse 9] so [they would have verification that] my running [i.e., ministry] had not been, nor was now, in vain.
