The idiom "The word of Yahweh came to" is used to introduce a special message from God. See how you translated a similar phrase in Jeremiah 1:4, and make any changes as needed. Alternate translation: "Yahweh gave me a message a second time. He said" or "Yahweh spoke this second message to me" (See: rc://en/ta/man/translate/figs-idiom)
