Jeremiah 42:4-6 King James Version (KJV)
4 Then Jeremiah the prophet said unto them, I have heard you; behold, I will pray unto the Lord your God according to your words; and it shall come to pass, that whatsoever thing the Lord shall answer you, I will declare it unto you; I will keep nothing back from you.
5 Then they said to Jeremiah, The Lord be a true and faithful witness between us, if we do not even according to all things for the which the Lord thy God shall send thee to us.
6 Whether it be good, or whether it be evil, we will obey the voice of the Lord our God, to whom we send thee; that it may be well with us, when we obey the voice of the Lord our God.
Jeremiah 42:4-6 New International Version (NIV)
4 “I have heard you,” replied Jeremiah the prophet. “I will certainly pray to the Lord your God as you have requested; I will tell you everything the Lord says and will keep nothing back from you.”
5 Then they said to Jeremiah, “May the Lord be a true and faithful witness against us if we do not act in accordance with everything the Lord your God sends you to tell us. 6 Whether it is favorable or unfavorable, we will obey the Lord our God, to whom we are sending you, so that it will go well with us, for we will obey the Lord our God.”
