Isaiah 21:6-8

Revised Standard Version Catholic Edition

⁶ For thus the Lord said to me:
“Go, set a watchman,
    let him announce what he sees.
⁷ When he sees riders, horsemen in pairs,
    riders on asses, riders on camels,
let him listen diligently,
    very diligently.”
⁸ Then he who saw^[a] cried:
“Upon a watchtower I stand, O Lord,
    continually by day,
and at my post I am stationed
    whole nights.
