'Enduring' in the Bible

“Behold, I am bringing a nation against you from far away, 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,Whose words you do not comprehend.

If I say, “I will not remember HimOr speak His name anymore,”Then my heart becomes a burning fireShut up in my bones.And I am weary of enduring and holding it in;I cannot endure it [nor contain it any longer].
