II. It is here spoken of as a great business, which ought to be managed with abundance of care and circumcision. When the liberty is proclaimed, 1. Let the people of God hasten out of Babylon with all convenient speed; though they are ever so well settled there, let them not think of taking root in Babylon, but Depart, depart (v. 11), go out from the midst of her; not only those that are in the borders, but those that are in the midst, in the heart of the country, let them be gone. Babylon is no place for Israelites. As soon as they have leave to let go, let them lose no time. With this word God stirred up the spirits of those that were moved to go up, Ezra i. 5. And it is a call to all those who are yet in the bondage of sin and Satan to make use of the liberty which Christ has proclaimed to them. And, if the Son make them free, they shall be free indeed. 2. Let them take heed of carrying away with them any of the pollutions of Babylon: Touch no unclean thing. Now that God makes bare his holy arm for you, be you holy as he is, and keep yourselves from every wicked thing. When they came out of Egypt they brought with them the idolatrous customs of Egypt (Ezek. xxiii. 3), which were their ruin; let them take heed of doing so now that they come out of Babylon. Note, When we are receiving any special mercy from God we ought more carefully than ever to watch against all impurity. But especially let those be clean who bear the vessels of the Lord, that is, the priests, who had the charge of the vessels of the sanctuary (when they were restored by a particular grant) to carry them to Jerusalem, Ezra i. 7; viii. 24, &c. Let them not only avoid touching any unclean thing, but be very careful to cleanse themselves according to the purification of the sanctuary. Christians are made to our God spiritual priests, Rev. i. 6. They are to bear the vessels of the Lord, are entrusted to keep the ordinances of God pure and entire; it is a good thing that is committed to them, and they ought to be clean, to wash their hands in innocency and so to compass God's altars and carry his vessels, and keep themselves pure. 3. Let them depend upon the presence of God with them and his protection in their removal (v. 12): You shall not go out with haste. They were to go with a diligent haste, not to lose time nor linger as Lot in Sodom, but they were not to go with a diffident distrustful haste, as if they were afraid of being pursued (as when they came out of Egypt) or of having the orders for their release recalled and countermanded: no, they shall find that, as for God, his work is perfect, and therefore they need not make more haste than good speed. Cyrus shall give them an honourable discharge, and they shall have an honourable return, and not steal away; for the Lord will go before them as their general and commander-in-chief, and the God of Israel will be their rearward, or he that will gather up those that are left behind. God will both lead their van and bring up their rear; he will secure them from enemies that either meet them or follow them, for with his favour will he compass them. The pillar of cloud and fire, when they came out of Egypt, sometimes went behind them, to secure their rear (Exod. xiv. 19), and God's presence with them would now be that to them which that pillar was a visible token of. Those that are in the way of their duty are under God's special protection; and he that believes this will not make haste.
