Jeremiah 1:18-19

18I, the Lord, promise that I will make you as strong as a city with strong walls around it. You will be as strong as an iron pillar, or a wall that is made of bronze. You will speak a message against the whole nation of Judah. You will speak against its kings, its officers, its priests and all its people.

19They will attack you. But they will not win against you, because I will be with you. I will keep you safe. That is what the Lord says.’
