And as the mariners sought. The grace of the Holy Spirit appeareth in Paul, even in this point also, in that he did wisely admonish that the mariners should not be suffered to fly. For why doth not rather the centurion, or some other of the company, smell out their fraud, save only that Paul may be the minister of their deliverance, even unto the end? But it is a marvel that he saith, that the rest could not be saved unless the mariners should remain in the ship; as if it were in their power to make the promise of God of none effect. I answer, that Paul doth not dispute, in this place, precisely of the power of God, that he may separate the same from his will and from means; and surely God doth not, therefore, commend his power to the faithful, that they may give themselves to sluggishness and carelessness, contemning means, or rashly cast away themselves when there is some certain way to escape. God did promise Hezekiah that the city should be delivered (Isaiah 37:6, and 35). If he had set open the gates to the enemy, would not Isaiah straightway have cried, Thou destroyest both thyself and the city? And yet for all this it doth not follow that the hand of God is tied to means or helps; but when God appointeth this or that means to bring any thing to pass, he holdeth all men's senses, that they may not pass the bounds which he hath appointed.

The shipmen - The sailors, leaving the prisoners.
Under colour - Under pretence. They pretended that it was necessary to get into the boat, and carry the anchors ahead of the ship so as to make it secure, but with a real intention to make for the shore.
Out of the foreship - From the prow, so as to make the fore-part of the ship secure. The reason why they did this was probably that they expected the ship would go to pieces; and, since all on board could not be saved in one small boat, they resolved to escape to a place of safety as soon as possible.

The shipmen - The sailors - let down the boat. Having lowered the boat from the deck into the sea, they pretended that it was necessary to carry some anchors ahead, to keep her from being carried in a dangerous direction by the tide, but with the real design to make for shore, and so leave the prisoners and the passengers to their fate. This was timely noticed by the pious and prudent apostle; who, while simply depending on the promise of God, was watching for the safety and comfort of all.

(8) And as the shipmen were about to flee out of the ship, when they had let down the boat into the sea, under colour as though they would have cast anchors out of the foreship,
(8) No matter how foul the act, distrust and an evil conscience can always compel men to commit it.

And as the shipmen were about to flee out of the ship,.... To save their lives, concluding that it was in the utmost danger, and that it would quickly, notwithstanding the anchors cast out, break away, and fall upon the rocks, and split to pieces:
when they had let down the boat into the sea; which before they had taken up into the ship, Acts 27:16 and now they let it down, in order to get into it, and make their escape:
under colour as though they would have cast anchors out of the foreship; the foremost part of the ship, the prow of it; their pretence in attempting to get out of the ship, and into the boat, was, that whereas there were anchors cast out of the stern, or hinder part of the ship, so they would cast out others, from the fore part of it; and "stretch" them "out", as the word signifies, or carry them further out into the sea, for the security of the ship; and to do which, it was necessary to use the boat.

God, who appointed the end, that they should be saved, appointed the means, that they should be saved by the help of these shipmen. Duty is ours, events are God's; we do not trust God, but tempt him, when we say we put ourselves under his protection, if we do not use proper means, such as are within our power, for our safety. But how selfish are men in general, often even ready to seek their own safety by the destruction of others! Happy those who have such a one as Paul in their company, who not only had intercourse with Heaven, but was of an enlivening spirit to those about him. The sorrow of the world works death, while joy in God is life and peace in the greatest distresses and dangers. The comfort of God's promises can only be ours by believing dependence on him, to fulfil his word to us; and the salvation he reveals must be waited for in use of the means he appoints. If God has chosen us to salvation, he has also appointed that we shall obtain it by repentance, faith, prayer, and persevering obedience; it is fatal presumption to expect it in any other way. It is an encouragement to people to commit themselves to Christ as their Saviour, when those who invite them, clearly show that they do so themselves.

as the shipmen were about to flee out of the ship--under cover of night.
when they had let down the boat . . . as though they would . . . cast anchors out of the foreship--"bow"--rather, "carry out" anchors, to hold the ship fore as well as aft. "This could have been of no advantage in the circumstances, and as the pretext could not deceive a seaman, we must infer that the officers of the ship were parties to the unworthy attempt, which was perhaps detected by the nautical skill of St. Luke, and communicated by him to St. Paul" [SMITH].

The sailors were attempting to flee out of the ship - Supposing the boat would go more safely over the shallows.
