Ezra1chapter 1

Cyrus took Babylon in October 539 BC, and within about a year he had issued the decree that opens this book: the God of heaven has charged me to build Him a house at Jerusalem; whoever is among His people, let him go up.

That was Persian policy, not a personal conversion. Persia governed differently from Assyria and Babylon, who had ruled by mass deportation. Cyrus preferred to send peoples back to their homelands, restore their shrines, and let them worship their own gods — on the reasonable calculation that grateful provinces need fewer garrisons.

The famous physical evidence is the Cyrus Cylinder, a clay barrel inscribed in Babylonian, now in the British Museum. It describes Cyrus returning gods to their sanctuaries and people to their settlements. It does not mention Judah or Jerusalem by name — it is a Mesopotamian document about Mesopotamian shrines — but it shows the policy this decree belongs to, which is exactly why it matters.

The vessels are the detail worth watching. Nebuchadnezzar had carried the temple's gold and silver articles to Babylon and put them in the house of his gods; Belshazzar had drunk from them at his last feast. Cyrus has them counted out of the treasury — 5,400 items — and handed over to a man named Sheshbazzar.

The returnees' neighbors are told to help with silver, gold, goods, and animals, which echoes the Israelites leaving Egypt with their neighbors' silver. The comparison is deliberate.
