7 Bible Verses about Unknown Languages

When Israel went out from Egypt, the house of Jacob from a people of strange language,

The LORD will bring a nation against you from far away, from the end of the earth, swooping down like the eagle, a nation whose language you do not understand,

Behold, I am bringing against you a nation from afar, O house of Israel, declares the LORD. It is an enduring nation; it is an ancient nation, a nation whose language you do not know, nor can you understand what they say.

For by people of strange lips and with a foreign tongue the LORD will speak to this people,

In the Law it is written, "By people of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord."

You will see no more the insolent people, the people of an obscure speech that you cannot comprehend, stammering in a tongue that you cannot understand.

For you are not sent to a people of foreign speech and a hard language, but to the house of Israel-- not to many peoples of foreign speech and a hard language, whose words you cannot understand. Surely, if I sent you to such, they would listen to you.
