'Influential' in the Bible

Now I went up [there] because of a revelation and laid out to them the gospel that I preach among the Gentiles, but in private to the influential people, lest somehow I was running, or had run, in vain.

But from those {who were influential} (whatever they were, [it makes] no difference to me, {God does not show partiality})--for those who were influential added nothing to me.
