This idiom is used to introduce a special message from God. See how you translated it in [Jeremiah 1:4](../01/04.md). Alternate translation: "Yahweh gave me a message. He said, 'Yahweh" or "Yahweh spoke this message to me: 'Yahweh" (See: [[rc://en/ta/man/translate/figs-idiom]])
Here "look on" is an idiom that means Yahweh will take care of them. Alternate translation: "I will take good care of the exiles of Judah" (See: [[rc://en/ta/man/translate/figs-idiom]])
