And many people shall go Shall not only have some weak desires of going, but shall take pains, and actually go; and say, Come, &c. Yea, such shall be their zeal, that they shall not only go themselves, but shall persuade and press others to go with them. And we will walk in his paths Thus they show the truth of their conversion, by their hearty desire to be instructed in the way of worshipping and serving God acceptably, and by their firm purpose of practising the instructions given. For out of Zion shall go forth the law The new law, the doctrine of the gospel, which is frequently called a law, because it hath the nature and power of a law, obliging us no less to the belief and practice of it than the old law did; and the word of the Lord For the accomplishment of this promise, see Luke 24:47; Acts 1:8; Romans 10:18. This last clause shows the reason why the people should be so forward to go, and to invite others to go with them.
