Yahweh speaks of how the cities of Jerusalem and Samaria have been unfaithful to him in a metaphor in which he refers to them as two sexually immoral women. This metaphor continues through Ezekiel 23:34. (See: [[rc://en/ta/man/jit/figs-metaphor]])
This is an idiom that is used to introduce something that God told his prophets or his people. See how you translated this in [Ezekiel 3:16](../03/16.md). Alternate translation: "Yahweh spoke this message" or "Yahweh spoke these words" (See: [[rc://en/ta/man/jit/figs-idiom]])
