At first glance there is not much that combines the New and old Testament readings selected for today. In John 6:1-24. Jesus performed miracles 4 and 5 recorded by the Apostle John, feeding 5000 (plus women and children) and then during the night walking on water.
Then in the Old Testament Genesis 11 it tells about the Tower of Babel, and how different languages arose, all by being disobedient to God.
Then again in Psalm 3 David prayed earnestly when he fled from his son Absalom.
The common thread is we always seek to get some favors from God, and thus be able to control the outcome. But God.
