The career of one of these giants is a pictorial exhibition of this principle of the spiritual harvest.

Young Jacob was shrewd, crafty and full of foresight.

If Esau, his brother, was a "hail fellow well met," the child of his impulses, Jacob was a diplomat and very wily.

One day, when the father, Isaac, was blind and old, Esau grew restless, and at last went away with his companions, for he dearly loved to hunt.

In that hour ambition tempted Jacob and avarice led him away.
