The sentinels on the wall (Isa 62:6-62:7)

“O Jerusalem!

Upon your walls

I have set sentinels.

All day,

All night,

They shall never be silent.

You who remind Yahweh!

Take no rest!

Give him no rest

Until he establishes Jerusalem!

Until he makes it renowned

Throughout the earth!”

Yahweh was going to put sentinels or watchmen on the walls, day and night, that would never be silent. They were there to remind Yahweh that he was not to rest until Jerusalem had been established and known throughout the world.
