וּבְבֹאָ֑הּ הִנֵּ֣ה בָאָ֔ה וְיָ֣דְע֔וּ כִּ֥י נָבִ֖יא הָיָ֥ה בְתוֹכָֽם׃ (ס)
Tetapi apabila hal itu terjadi, dan sesungguhnya hal itu pasti datang, maka mereka akan mengetahui bahwa seorang nabi telah ada di tengah-tengah mereka.
Rashi
behold it is coming for, indeed, it is ready to come; then they will know that your words were not a jest, but that a true prophet was in their midst.
