Based on the Old Testament prophecies the Koresh foundation feels called to inform believers outside of Israel regarding Biblical fact, that it is Gods will for 'strangers' to support the restoration of Israel, meaning the people of Israel as well as the Land Israel.
Isaiah 14:1 "Yahweh will have compassion for Jacob and again choose Israel. He will resettle them in their own country. Foreigners will join them and unite with the descendants of Jacob."
Isaiah 60:10 "“Foreigners will rebuild your walls, and their kings will serve you. In my anger I struck you, but in my favor I have compassion on you."
Also with regard to King Koresh: Isaiah 44:28 "He says about Cyrus (= Koresh), “He is my shepherd. He will do everything I want him to do.” He says about Jerusalem, “It will be rebuilt.” He says about the temple, “Your foundation will be laid.”
