(15) But know ye for certain.--Literally, with the Hebrew emphasis of reduplication, Knowing, know ye. The appeal is addressed, it will be remembered, to the lay judges, the princes, and the people, not to the priests and prophets who accused him. He believes that they at least would shrink from shedding innocent blood. And he solemnly protests that he is innocent of any wilful attack upon what his countrymen revered. He has spoken, but it has been by a constraint above his own will. A "necessity has been laid upon him" (1Corinthians 9:16).

26:7-15 The priests and prophets charged Jeremiah as deserving death, and bore false witness against him. The elders of Israel came to inquire into this matter. Jeremiah declares that the Lord sent him to prophesy thus. As long as ministers keep close to the word they have from God, they need not fear. And those are very unjust who complain of ministers for preaching of hell and damnation; for it is from a desire to bring them to heaven and salvation. Jeremiah warns them of their danger if they go on against him. All men may know, that to hurt, or put to death, or to show hatred to their faithful reprovers, will hasten and increase their own punishment.But know ye for certain, that if ye put me to death,.... Take this along with you, and then do as you will; that if ye take away my life on this account, you may depend upon it; nothing is more certain than this:

ye shall surely bring innocent blood upon yourselves, and upon this city, and upon the inhabitants thereof; that is, the guilt of innocent blood, which would cry for vengeance upon them that brought the accusation, and insisted upon his being brought in guilty; and upon those that sat in judgment, and condemned him; and upon all the inhabitants of the city of Jerusalem, who should agree to the putting him to death:

for of a truth the Lord hath sent me unto you to speak all these words in your ears; and therefore I am no false prophet, and am clear of the charge brought against me; and have said nothing but what I had a mission and an order from the Lord for, of which you may assure yourselves; and therefore he will avenge my blood, should it be shed on that account; so that you will only increase your guilt, and add to that great load that lies upon you, and will be your ruin, unless you repent and reform.
