John Gill Commentary Acts 24:22

"But Felix, having more exact knowledge concerning the Way, deferred them, saying, When Lysias the chief captain shall come down, I will determine your matter." — Acts 24:22 (ASV)

And when Felix heard these things
Which were said on both sides, both by plaintiff and defendant, the charges brought against Paul, and his answer to them, as a judge ought to do:

having more perfect knowledge of that way ;
the Christian religion, which the Jews called heresy, and Paul had embraced; the sense is, either that he had a more perfect knowledge of it than he had before; and by what Paul had said, he saw that it was not contrary to the law, nor had any tendency to promote sedition and tumult; or rather, when he should have more perfect knowledge of this new way, called the sect of the Nazarenes, he would determine this cause, and not before: wherefore

he deferred
them; put them off to longer time, and would make no decision in favour of one side or the other:

and said, when Lysias the chief captain shall come
from Jerusalem to Caesarea,

I will know the uttermost of your matters :
as for the way, or religion of the Christians, he proposed doubtless to consult other persons; and as for the profanation of the temple, and especially about stirring up of sedition, he would inquire of Lysias about that; and when he had got full information of these particulars, then he promised them to bring things to an issue, and finish the cause.
