IV. This shall redound very much both to the glory of God and to the comfort and satisfaction of his people. 1. It shall be much for the honour of God, for the heathen shall hereby be made to know that he is the Lord (v. 21): All the heathen shall see and observe my judgments that I have executed, and thereby my glory shall be set among them. This principle shall be admitted and established among them more than ever, that the God of Israel is a great and glorious God. He is known to be so even among the heathen, that have not, or read not, his written word, by the judgments which he executes. 2. It shall be much for the satisfaction of his people; for they shall hereby be made to know that he is their God (v. 22): The house of Israel shall know, abundantly to their comfort, that I am the Lord their God from that day and forward. (1.) He will be so from that day and forward. God's present mercies are pledges and assurances of further mercies. If God evidence to us that he is our God he assures us that he will never leave us. This God is our God for ever and ever. (2.) They shall know it with more satisfaction from that day and forward. They had sometimes been ready to question whether the Lord was with them or no; but the events of this day shall silence their doubts, and, the matter being thus settled and made clear, it shall not be doubted of for the future. As boasting in themselves is hereby for ever excluded, so boasting in God is hereby for ever secured.
