Ezekiel 37:21 - Ellicott's Commentary On The Whole Bible

Will gather them. — The restoration of Israel from their captivity among the heathen here, as often elsewhere, is the first step in the fulfilment of the Divine promises. This, however, like the other Divine promises, was fulfilled only to a “remnant,” a course which, as St. Paul shows in Romans 9, had been foreseen and foretold from the first. A fulfilment on a larger scale was perpetually prevented by the sins of the people; God did for them all that their obdurate disobedience would allow Him to do. Yet He did not wholly reject them, but allowed a remnant to keep alive His Church, and become the channel of those richer blessings of the new covenant, in which all who will accept His salvation are united in a holier bond, and led to a land of higher promise than Israel after the flesh could ever know.
