Aliya Summary: When G‑d gathers His people’s exiles, the curses which accompanied them throughout their sojourn in foreign lands will be placed upon their enemies who persecuted them. The Israelites will once again serve G‑d, and will be blessed with abundance in the work of their hands, the fruit of their wombs, the fruit of their land, and the fruit of their livestock.
If (when) we return to G-d, then G-d will rain the curses upon our enemies. We have only to be faithful to HaShem and keep His mitzvot, and all His blessings will be showered upon us. Again a “pitch” is made for T’shuva. And again. And the T’shuva should be completely sincere.
