וַיַּעֲשׂ֨וּ בְנֵֽי־יִשְׂרָאֵ֧ל הַֽנִּמְצְאִ֛ים אֶת־הַפֶּ֖סַח בָּעֵ֣ת הַהִ֑יא וְאֶת־חַ֥ג הַמַּצּ֖וֹת שִׁבְעַ֥ת יָמִֽים׃
Und die anwesenden Kinder Israel hielten zu dieser Zeit das Passah und sieben Tage lang das Fest der ungesäuerten Brote.
Rashi
Go and proclaim, etc. Go, as the Targum renders, אזיל, the imperative form. Here he commanded him to go and bring back the Ten Tribes during the days of Josiah, as he states above that during the days of Josiah this prophecy was said to him and some of them returned in the eighteenth year of Josiah.
