Jeremiah 5:14-16

14Wherefore thus saith the Lord God of hosts, Because ye speak this word, behold, I will make my words in thy mouth fire, and this people wood, and it shall devour them.

15Lo, I will bring a nation upon you from far, O house of Israel, saith the Lord: it is a mighty nation, it is an ancient nation, a nation whose language thou knowest not, neither understandest what they say.

16Their quiver is as an open sepulchre, they are all mighty men.
