Sermon Crumbs: The last part of today’s sermon text, Psalm 40:13-17, is almost identical to Psalm 70.  Scholars speculate without consensus on the relationship of these two psalms, but perhaps it doesn’t matter: modern hymnals contain nearly identical lyrics set to different tunes for different occasions; why should Israel’s hymnal be any different?  Also, Psalm 40:6 is quoted with somewhat different wording in Hebrews 10:5, where it is applied to Christ.  Hebrews cites the Greek translation of the OT, which accounts for the difference.
