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.
I have heard you - i:e., I accede to your request.
The Lord your God. Being His by adoption, ye are not your own, and are bound to whatever He wills (Exodus 19:5-6; 1 Corinthians 6:19-20).
Whatsoever thing the Lord shall answer you - i:e., through me.
I will keep nothing back - (1 Samuel 3:18; Acts 20:20).
