Jeremiah 15:15-20 New Revised Standard Version (NRSV)
15 O Lord, you know;
remember me and visit me,
and bring down retribution for me on my persecutors.
In your forbearance do not take me away;
know that on your account I suffer insult.
16 Your words were found, and I ate them,
and your words became to me a joy
and the delight of my heart;
for I am called by your name,
O Lord, God of hosts.
17 I did not sit in the company of merrymakers,
nor did I rejoice;
under the weight of your hand I sat alone,
for you had filled me with indignation.
18 Why is my pain unceasing,
my wound incurable,
refusing to be healed?
Truly, you are to me like a deceitful brook,
like waters that fail.
19 Therefore thus says the Lord:
If you turn back, I will take you back,
and you shall stand before me.
If you utter what is precious, and not what is worthless,
you shall serve as my mouth.
It is they who will turn to you,
not you who will turn to them.
20 And I will make you to this people
a fortified wall of bronze;
they will fight against you,
but they shall not prevail over you,
for I am with you
to save you and deliver you,
says the Lord.
