Passports
The closest scriptural correspondence to a passport is a royal letter authorizing safe travel and access. One such instance is recorded when Nehemiah is dispatched from the Persian court to Jerusalem.
Letters Given to Nehemiah
Before leaving Susa, Nehemiah asks the king for written authorization that will carry him through the provinces and secure the materials he will need on arrival. He frames the petition explicitly: "Moreover I said to the king, If it pleases the king, let letters be given me to the governors beyond the River, that they may let me pass through until I come to Judah; and a letter to Asaph the keeper of the king's forest, that he may give me timber to make beams for the gates of the castle which pertains to the house, and for the wall of the city, and for the house that I will enter into. And the king granted me, according to the good hand of my God on me" (Neh 2:7-8).
The letters function on arrival exactly as requested: "Then I came to the governors beyond the River, and gave them the king's letters. Now the king had sent with me captains of the army and horsemen" (Neh 2:9). The royal seal, presented to provincial officials, secures both passage and protection across imperial territory.
