When Yahweh spoke at the first by Hosea, Yahweh said to Hosea, "Go, take for yourself a wife of prostitution and children of unfaithfulness; for the land commits great adultery against from Yahweh."
Second, some interpreters believe that Hosea’s wife became "a wife of harlotry" because she was already or became a worshipper of a false god; her harlotry was spiritual rather than physical. A related view is that she was a spiritual harlot merely by being an Israelite since the Israelites had been unfaithful to Yahweh. [Note: Stuart, pp. 26-27.] Again the details of the story as it unfolds argue for literal sexual unfaithfulness.
