TSK · Isaiah 33:19

Yahweh will bring a nation against you from far, from the end of the earth, as the eagle flies; a nation whose language you shall not understand;

But he will speak to this nation with stammering lips and in another language;

So Sennacherib king of Assyria departed, went away, returned to Nineveh, and stayed there.

For you are not sent to a people of a strange speech and of a hard language, but to the house of Israel;

In the law it is written, "By men of strange languages and by the lips of strangers I will speak to this people. Not even thus will they hear me, says the Lord."
