What does Isaiah 44:28 mean?

Cyrus is the one I call my shepherd. He’ll do everything I want. He’ll say about Jerusalem, 'Let it be rebuilt,' and about the temple, 'Lay its foundations again.' Isaiah 44:28 - Modern Text Bible

(God names Cyrus, a foreign king, as the one who will restore Jerusalem and the temple. This is shocking because Cyrus isn’t an Israelite, but God is using him to fulfill His promises.)
