(8) Gird thyself, and bind on thy sandals.--In lying down to sleep the Apostle had naturally laid aside his "cloak," loosened the girdle that bound his tunic, and put off his sandals. As regards the latter we note his continued observance of the rule of Mark 6:9.

Verse 8. - He did so for so he did, A.V. Thy garment (ἱμάτιον); especially the outer garment, which was worn over the χιτὼν, or tunic (see Matthew 9:20, 21; Matthew 14:36; Matthew 23:5, etc.). The girding, therefore, applied to the inner garments, and περιβαλοῦ το the cloak which went over them.

12:6-11 A peaceful conscience, a lively hope, and the consolations of the Holy Spirit, can keep men calm in the full prospect of death; even those very persons who have been most distracted with terrors on that account. God's time to help, is when things are brought to the last extremity. Peter was assured that the Lord would cause this trial to end in the way that should be most for his glory. Those who are delivered out of spiritual imprisonment must follow their Deliverer, like the Israelites when they went out of the house of bondage. They knew not whither they went, but knew whom they followed. When God will work salvation for his people, all difficulties in their way will be overcome, even gates of iron are made to open of their own accord. This deliverance of Peter represents our redemption by Christ, which not only proclaims liberty to the captives, but brings them out of the prison-house. Peter, when he recollected himself, perceived what great things God had done for him. Thus souls delivered out of spiritual bondage, are not at first aware what God has wrought in them; many have the truth of grace, that want evidence of it. But when the Comforter comes, whom the Father will send, sooner or later, he will let them know what a blessed change is wrought.And the angel said unto him, gird thyself,.... He slept in his inner garment loose about him; wherefore the angel bids him gird it up with his girdle, and prepare to walk out after him:

and bind on thy sandals; which were a sort of shoes that covered only the soles of the feet, and were fastened to the leg, with strings:

and so he did; he did not ask any question, or the reason of these orders; he did not dispute the matter, but at once obeyed:

and he saith unto him, cast thy garment about thee; meaning his upper garment, or cloak, which lay by him:

and follow me; suggesting hereby, that he should take care of him, and show him his way, and bring him safe out of the prison.
