John Gill Commentary Acts 28:18

"who, when they had examined me, desired to set me at liberty, because there was no cause of death in me." — Acts 28:18 (ASV)

Who when they had examined me About the things laid to his charge, had heard what his accusers had to object to him, and the defence he made for himself:

would have let [me] go ; released him from his bonds, and set him at liberty to go where he pleased:

because there was no cause of death in me ; no crime proved upon him, which was worthy of death; and this was the sense of Lysias the chief captain, and of Felix and Festus the Roman governors, and of King Agrippa.
