Jeremiah 42:2-4, 20

and said unto Jeremiah the prophet, Let, we beseech thee, our supplication be accepted before thee, and pray for us unto the LORD thy God, even for all this remnant; (for we are left but a few of many, as thine eyes do behold us:) that the LORD thy God may shew us the way wherein we may walk, and the thing that we may do. 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.

For ye dissembled in your hearts, when ye sent me unto the LORD your God, saying, Pray for us unto the LORD our God; and according unto all that the LORD our God shall say, so declare unto us, and we will do it.
