When Israel came forth out of Egypt, the house of Jacob from a people of strange language,
The Lord will bring a nation against you from afar, from the end of the earth, as swift as the eagle flies, a nation whose language you shall not understand,
Behold, I am bringing a nation upon you from afar, O house of Israel, says the Lord. It is a mighty and enduring nation, it is an ancient nation, a nation whose language you do not know, nor can you understand what they say.
No, but [the Lord will teach the rebels in a more humiliating way] by men with stammering lips and another tongue will He speak to this people [says Isaiah, and teach them His lessons].
1 Corinthians 14:21
It is written in the Law, By men of strange languages and by the lips of foreigners will I speak to this people, and not even then will they listen to Me, says the Lord.
You will see no more the fierce and insolent people, a people of a speech too deep and obscure to be comprehended, of a strange and stammering tongue that you cannot understand.
For you are not sent to a people of a foreign speech and of a difficult language but to the house of Israel; Not to many peoples of foreign speech and of a hard language, whose words you cannot understand. Surely, had I sent you to such people, they would have listened to you and heeded My words.
