ישעיהו יח:ג פירוש: רש״י ואבן עזרא

All inhabitants of the world, etc. You need not send messengers for this, for when a standard of the mountains is raised, you shall see the ingathering of the exiles, and when a shofar is sounded you shall hear.

All ye inhabitants of the world. As if a banner were raised over the whole earth.

You shall hear, so as to know the work of the Lord, which He has done in the camp of Sennacherib.
