Jeremiah 1:10

See, I have this day set thee over the nations and over the kingdoms, the naturally timid and fearful prophet being appointed to their oversight, to root out, and to pull down, and to destroy, to extirpate, exterminate, and eliminate, and to throw down, to pronounce the divine judgment upon His enemies, to build and to plant, by announcing God's mercy and grace to all who heeded His call. The conditions in Judah were such at that time as to provoke threatenings and rebukes on the part of the Lord rather than promises of grace and mercy.
