Isaiah 21:6-8

New Revised Standard Version, Anglicised Catholic Edition

⁶ For thus the Lord said to me:
‘Go, post a lookout,
    let him announce what he sees.
⁷ When he sees riders, horsemen in pairs,
    riders on donkeys, riders on camels,
let him listen diligently,
    very diligently.’
⁸ Then the watcher^[a] called out:
‘Upon a watch-tower I stand, O Lord,
    continually by day,
and at my post I am stationed
    throughout the night.
