Jeremiah 15:20

And I will make thee unto this people a fenced brasen wall ,.... As he had promised him, when he first called him to his office, Jeremiah 1:18 , and so would not be as a liar to him:

and they shall fight against thee ; by words and blows, by menaces and imprisonment:

but they shall not prevail against thee ; so as to cause him to call in his words, and contradict his prophecies; or so as to take away his life:

for I am with thee, to save thee, and deliver thee, saith the Lord ; the presence of God with his ministers is sufficient to save and deliver them out of all their troubles, and to protect and defend them against all their enemies; see Matthew 28:20 .
