Both Yerovam and Shaul turn to the prophet that appointed them at their time of need. In both cases, the navi who appoints the king announces their rejection. Yerovam sends his wife to ask about their son, but why must she be disguised? Ahiya, prophecy is damning both for Yerovam - in a harsh and grotesque language - and for the entire nation. However, the parable and language that Ahiya uses for the punishement of the nation mitigates his message and gives hope.
