Adam Clarke on Psalms 130:6

More than they that watch for the morning - I believe the original should be read differently from what it is here. The Chaldee has, "More than they who observe the morning watches, that they may offer the morning oblation." This gives a good sense, and is, perhaps, the true meaning. Most of the Versions have "From the morning to the night watches." Or the passage may be rendered, "My soul waiteth for the Lord from the morning watches to the morning watches." That is, "I wait both day and night."
