Imagine city walls at night. Who stands guard? Isaiah speaks of 'watchmen,' but not just for physical threats. These are spiritual sentinels, and their work is never done.
In Isaiah 62:6, God declares, 'I have set watchmen upon your walls, O Jerusalem.' These aren't just ordinary guards; they are appointed by God Himself.
A Perpetual Duty
The text emphasizes their tireless nature: 'all the day and all the night they shall never be silent.' This isn't about taking shifts; it's about a constant, unwavering commitment. The ancient Near East had a practice of watchmen crying out periodically through the night to mark the time and signal their vigilance. This imagery conveys a profound sense of continuous engagement.
More Than Vigilance
These watchmen are tasked with more than just spotting danger. They are to be 'the LORD's remembrancers' – those who keep God's promises and purposes alive in prayer and proclamation. Their silence would mean a failure in their divine commission, allowing spiritual threats and forgetfulness to creep in.
