I. He invites them into their chambers (v. 20): "Come, my people, come to me, come with me" (he calls them nowhere but where he himself will accompany them); "let the storm that disperses others bring you nearer together. Come, and enter into thy chambers; stay not abroad, lest you be caught in the storm, as the Egyptians in the hail," Exod. ix. 21. 1. "Come into chambers of distinction; come into your own apartments, and continue not any longer mixed with the children of Babylon. Come out from among them, and be you separate," 2 Cor. vi. 17; Rev. xviii. 4. If God has set apart those that are godly for himself, they ought to set themselves apart. 2. "Into chambers of defence, in which by the secresy or the strength of them you may be safe in the worst of times." The attributes of God are the secret of his tabernacle, Ps. xxvii. 5. His name is a strong tower, into which we may run for shelter, Prov. xviii. 10. We must by faith find a way into these chambers, and there hide ourselves; that is, with a holy security and serenity of mind, we must put ourselves under the divine protection. Come, as Noah into the ark, for he shut the doors about him. When dangers are threatening it is good to retire, and lie hid, as Elijah did by the brook Cherith. 3. Into chambers of devotion. "Enter into thy closet, and shut thy door, Matt. vi. 6. Be private with God: Enter into thy chamber, to examine thyself, and commune with thy own heart, to pray, and humble thyself before God." This work is to be done in times of distress and danger; and thus we hide ourselves, that is, we recommend ourselves to God to hide us, and he will hide us either under heaven or in heaven. Israel must keep within doors when the destroying angel is slaying the first-born of Egypt, else the blood on the door-posts will not secure them. So must Rahab and her family when Jericho is being destroyed. Those are most safe that are least seen. Qui bene latuit, benevixit—He has lived well who has sought a proper degree of concealment.
