“O Key of David and Sceptre of Israel,
what you open no one else can close again;
what you close no one can open.
O come to lead the captive from prison;
free those who sit in darkness and in the shadow of death.”
In the time of the prophet Isaiah, the king of Damascus and the king of Israel wanted to draw the king of Judah, Ahaz, into a coalition against Assyria. When he refused, the anti-Assyrian alliance attacked him and Ahaz, frightened, turned to the Assyrian for help. Isaiah opposed the request for help from the king of Assyria and exhorted Ahaz to put his trust only in the Lord.
