Would have killed himself - This was done in the midst of agitation and alarm. He supposed that the prisoners had fled. He presumed that their escape would be charged on him. It was customary to hold a jailor responsible for the safe keeping of prisoners, and to subject him to the punishment due them if he suffered them to escape. See Acts 12:19. It should be added that it was common and approved among the Greeks and Romans for a man to commit suicide when he was encompassed with dangers from which he could not escape. Thus, Cato was guilty of self-murder in Utica; and thus, at this very place - Philippi - Brutus and Cassius, and many of their friends, fell on their own swords, and ended their lives by suicide. The custom was thus sanctioned by the authority and example of the great; and we are not to wonder that the jailor, in a moment of alarm, should also attempt to destroy his own life. It is not one of the least benefits of Christianity that it has proclaimed the evil of self-murder, and has done so much to drive it from the world.

The keeper of the prison - would have killed himself - Every jailor was made responsible for his prisoner, under the same penalty to which the prisoner himself was exposed. The jailor, awaking, and finding the prison-doors open, taking it for granted that all the prisoners had made their escape, and that he must lose his life on the account, chose rather to die by his own hand than by that of others. For it was customary among the heathens, when they found death inevitable, to take away their own lives. This custom was applauded by their philosophers, and sanctioned by some of their greatest men.

And the keeper of the prison awaking out of his sleep,.... Not so much by the loud voices of Paul and Silas, as by the uncommon motion of the earth, which so shook him, as thoroughly to awake him:

and seeing the prison doors open; which was the first thing in his fright he was looking after, and careful of, and which he might perceive, though it was midnight, and though as yet he had no light:

he drew out his sword; from its scabbard, which was girt about him; for it may be he had slept with his clothes on, and his sword girt to him; or if he had put on his clothes upon awaking, he had also girt himself with his sword:

and would have killed himself, supposing that the prisoners had been fled; especially Paul and Silas, concerning whom he had received such a strict charge from the magistrates; and he knew that according to law, he must suffer the same punishment that was designed for them; and therefore in fear of the magistrates, and what they would inflict upon him, he was just going to destroy himself.

Would have killed (ἔμελλεν ἀναιρεῖν)

Rev., more correctly, was about to kill. Knowing that he must suffer death for the escape of his prisoners.

{16} And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled.

(16) The merciful Lord, as often as he desires, draws men to life even through the midst of death, and whereas they justly deserved great punishment, he shows them great mercy.

16:27 The keeper... drew out his sword. He was responsible with his life for the safety of his prisoners. Fancying them gone, he determined, like a Roman, to anticipate disgrace by death. Right there at Philippi, Brutus and Cassius had each inflicted self-death. Self-murder was very common among the Romans.

27. the keeper . awaking . drew . his sword, and would have killed himself, &c.-knowing that his life was forfeited in that case (Ac 12:19; and compare Ac 27:42).

16:25-34 The consolations of God to his suffering servants are neither few nor small. How much more happy are true Christians than their prosperous enemies! As in the dark, so out of the depths, we may cry unto God. No place, no time is amiss for prayer, if the heart be lifted up to God. No trouble, however grievous, should hinder us from praise. Christianity proves itself to be of God, in that it obliges us to be just to our own lives. Paul cried aloud to make the jailer hear, and to make him heed, saying, Do thyself no harm. All the cautions of the word of God against sin, and all appearances of it, and approaches to it, have this tendency. Man, woman, do not ruin thyself; hurt not thyself, and then none else can hurt thee; do not sin, for nothing but that can hurt thee. Even as to the body, we are cautioned against the sins which do harm to that. Converting grace changes people's language of and to good people and good ministers. How serious the jailer's inquiry! His salvation becomes his great concern; that lies nearest his heart, which before was furthest from his thoughts. It is his own precious soul that he is concerned about. Those who are thoroughly convinced of sin, and truly concerned about their salvation, will give themselves up to Christ. Here is the sum of the whole gospel, the covenant of grace in a few words; Believe in the Lord Jesus Christ, and thou shalt be saved, and thy house. The Lord so blessed the word, that the jailer was at once softened and humbled. He treated them with kindness and compassion, and, professing faith in Christ, was baptized in that name, with his family. The Spirit of grace worked such a strong faith in them, as did away further doubt; and Paul and Silas knew by the Spirit, that a work of God was wrought in them. When sinners are thus converted, they will love and honour those whom they before despised and hated, and will seek to lessen the suffering they before desired to increase. When the fruits of faith begin to appear, terrors will be followed by confidence and joy in God.
