Jeremiah 42:2-5

and said unto Jeremiah the prophet, Let, we pray thee, our supplication be presented before thee, and pray for us unto Jehovah thy God, even for all this remnant (for we are left but a few of many, as thine eyes do behold us), that Jehovah thy God may show us the way wherein we should walk, and the thing that we should do. Then Jeremiah the prophet said unto them, I have heard you; behold, I will pray unto Jehovah your God according to your words; and it shall come to pass that whatsoever thing Jehovah shall answer you, I will declare it unto you; I will keep nothing back from you. Then they said to Jeremiah, Jehovah be a true and faithful witness amongst us, if we do not according to all the word wherewith Jehovah thy God shall send thee to us.
