In the shadow of Mount Sinai, young priest Elior is tasked with transcribing the sacred laws that will govern a fragile nation. But as he records commandments of sacrifice and purity, he harbors a secret that could defile everything he writes. Centuries later, scholar Sarah Brenner discovers Elior's hidden marginalia within an ancient scroll—words that challenge the very foundation of ritual law. As her research threatens both her career and her faith, she must decide whether truth is worth breaking sacred silence. Leviticus weaves together two timelines in a haunting meditation on law, mercy, and the price of holiness.
