Ezekiel 28:25

Thus saith the Lord GOD; When I shall have gathered the house of Israel from the people among whom they are scattered, and shall be sanctified in them in the sight of the heathen, then shall they dwell in their land that I have given to my servant Jacob.

Ezekiel's work was a twenty-two-year pleading with Israel to turn to God, using the kingdoms on all sides of Israel as illustrations of how God has dealt with them and brought down their pride, with Tyre the great commercial city and Egypt the former oppressor presented as the two great nations judged. The verse stands in the description of Tyre given as an account of the anointed cherub, a beautiful angel who had been in the garden of God, who aspired to be like the Most High, in whom iniquity was found, and who was cast out from the midst of the stones of fire. It proves that the disobedient angels were in heaven and were cast out of heaven, degraded from their position and confined in tartarus, the region immediately surrounding this earth, reserved for judgment, and it denies that they were a pre-Adamic race on earth now dead and confined in the grave.

God himself, not Israel, will gather the scattered house of Israel from the people and nations among whom they are scattered and set them to dwell in their land, the land given to his servant Jacob. By means of this gathering God will be sanctified in Israel in the sight of the heathen, showing his holiness through them and before the nations.

That sanctifying is also shown before Israel itself through an enemy's delayed acknowledgment of His word and power. After God judges those who despise them, the gathered people dwell safely and with confidence, building houses and planting vineyards, and they know that He is their God.
