[Jehu] stand auf und ging hinein in das Haus. [Der Prophetenjünger] goß das Öl auf sein Haupt und sprach zu ihm: So hat gesprochen der Herr, der Gott Israels: Ich salbe dich zum König über das Volk des Herrn, über Israel.
Depths of Yonah
Yonah, in turn, was the perfect Navi to anoint Yeihu and inform him of his mission (see Melachim I 19:15-18) to utterly destroy the house of Achav (Melachim II 9:6-10). Accordingly, Yonah might have been indispensable as the Navi with the personality uniquely appropriate to communicate to Nineveh in the strongest terms that they will be completely wiped out if they do not immediately improve.
