Isaiah 62:6

Watchmen. It is the duty of the watchmen on the walls of Zion to guard its people against danger. In the ancient Orient danger constantly threatened, and it was necessary for watchmen to be ever on the alert. Every spiritual leader is a watchman, whose duty it is to stand guard upon the walls of Zion. See on ch. 21:11.

Day nor night. The work of a faithful minister is never done (see 2 Tim. 4:2). When others sleep he must remain on guard. When others are weary he must have courage and strength. He must be vigilant, industrious, unselfish, and alert, for on his fidelity depends the safety of the church. If he sleeps or falters, the enemy may gain a victory, and souls may be lost.

Make mention of the Lord. Literally, “causing to remember the Lord.” The spiritual watchman is accountable not only to his flock but also to God. He must at all times keep close to God, look to Him for counsel, and depend upon Him for strength. Day by day it is his task to present before the Lord the needs of his people and to make certain that their needs will be supplied. For Christ’s personal example see on Isa. 50:4; Mark 3:13; Luke 2:49.
