The answer of Jeremiah is simple and straightforward. Yahweh, he affirmed, had truly sent him, but the sole object of his prophesying had been to avert the evil by leading them to repentance. If they would amend their ways God would deliver them from the threatened doom. As for himself he was in their hands, but if they put him to death they would bring the guilt of shedding innocent blood upon themselves and upon the city.

Jeremiah 26:12-15
12 Then spake Jeremiah unto all the princes and to all the people, saying, The LORD sent me to prophesy against this house and against this city all the words that ye have heard.
13 Therefore now amend your ways and your doings, and obey the voice of the LORD your God; and the LORD will repent him of the evil that he hath pronounced against you.
14 As for me, behold, I am in your hand: do with me as seemeth good and meet unto you.
15 But know ye for certain, that if ye put me to death, ye shall surely bring innocent blood upon yourselves, and upon this city, and upon the inhabitants thereof: for of a truth the LORD hath sent me unto you to speak all these words in your ears.
