2 Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;
3 For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.
God told Israel to get ready for a great increase in numbers, for she would be restored to Palestine, her desolate cities would be inhabited, and she would even inherit the Gentiles and be a blessing to all the earth. Israel’s shame, confusion, and “widowhood” will be a thing of the past, and forgotten, when this is fulfilled. God will restore her, and her troubles will be no more. He will restore the nation and the city of Jerusalem, building them to be blessed eternally.
Best of all, the nation of Israel as a whole will return to the worship of and obedience to Jehovah, the Holy One of Israel.
