The Scofield Bible Commentary, by Cyrus Ingerson Scofield, [1917], at sacred-texts.com
Prayer
Prayer in the Old Testament is in contrast with prayer in the New Testament in two respects:

(2) A comparison, for example of the prayers of Moses and Paul, will show that one was praying for an earthly people whose dangers and blessings were earthly; the other for a heavenly people whose dangers and blessings were spiritual.
