Ezekiel 39:28

then shall they know that I am the Lord, their God, the true Israelites once more accepting Him as the God of the covenant, as the God of their salvation, which caused them to be led into captivity among the heathen, namely, with the express intention of bringing them to a realization of their foolishness and of their helplessness when they forsook Him; but I have gathered them unto their own land and have left none of them any more there. This applies to all those who were Israelites in truth, not only to those who actually returned to Canaan and took an active part in establishing the true worship, but also to those who remained in foreign lands, but were believers in the true God; for the latter had free access to their native land and to the Temple at Jerusalem as their spiritual dwelling-place.
