A priest from Anathoth, a small village near Jerusalem. He was young ("I am only a child") when God called him. He lived during the chaotic final days of the Kingdom of Judah.
God forbade him to marry or have children as a sign of the coming judgment. He was formed by Loneliness. He had to watch families celebrate while he stood alone.
He was formed by Predestination. "Before I formed you in the womb I knew you." His identity was set before he took a breath. He didn't choose this job; it chose him.
