John Gill Commentary Acts 26:31

"and when they had withdrawn, they spake one to another, saying, This man doeth nothing worthy of death or of bonds." — Acts 26:31 (ASV)

And when they were gone aside Into some apartment adjoining to the judgment hall.

they talked between themselves; that the common people might not hear their debates, and the result of them, and what were their sentiments concerning Paul and his case.

saying, this man doth nothing worthy of death, or of bonds; according to the Roman laws; for as yet there were no laws among the Romans against the Christians as such, or against their professing and preaching Christ.
