"But the arrival of the papal bulls laid upon all England a peremptory command for the arrest and imprisonment of the heretic. These measures pointed directly to the stake. It appeared certain that Wycliffe must soon fall a prey to the vengeance of Rome. But He who declared to one of old, “Fear not: ... I am thy shield” ( Genesis 15:1 ), again stretched out His hand to protect His servant. Death came, not to the Reformer, but to the pontiff who had decreed his destruction. Gregory XI died, and the ecclesiastics who had assembled for Wycliffe's trial, dispersed. GC 86.1"
"After these things the word of the Lord came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward."
Ellen White directly references Genesis 15:1 in this passage.
