"breaking forth of the waters, brought vividly to his mind the terrors of that awful outpouring of God's wrath. In the voice of many waters—deep calling unto deep—the prophet heard the voice of the Creator. The sea, lashed to fury by the merciless winds, represented to him the wrath of an offended God. The mighty waves, in their terrible commotion, restrained within limits appointed by an invisible hand, spoke of the control of an infinite Power. And in contrast he realized the weakness and folly of mortals, who, though but worms of the dust, glory in their supposed wisdom and strength, and set their hearts against the Ruler of the universe, as if God were altogether such a one as themselves. By the rocks he was reminded of Christ, the Rock of his strength, in whose shelter he could hide without fear. From the exiled apostle on rocky Patmos there went up the most ardent longing of soul after God, the most fervent prayers. AA 572.1"
"Deep calleth unto deep at the noise of thy waterspouts: all thy waves and thy billows are gone over me."
EGW directly references the concept of 'deep calling unto deep' and connects it to the 'voice of many waters,' which is a clear allusion to Psalm 42:7.
"And said, Hitherto shalt thou come, but no further: and here shall thy proud waves be stayed?"
Both passages discuss the power of God over the sea. EGW describes the sea as representing God's wrath and the waves being restrained by an invisible hand, while Job 38:11 directly quotes God commanding the sea to stop at a certain point.
"The history of John affords a striking illustration of the way in which God can use aged workers. When John was exiled to the Isle of Patmos, there were many who thought him to be past service, an old and broken reed, ready to fall at any time. But the Lord saw fit to use him still. Though banished from the scenes of his former labor, he did not cease to bear witness to the truth. Even in Patmos he made friends and converts. His was a message of joy, proclaiming a risen Saviour who on high was interceding for His people until He should return to take them to Himself. And it was after John had grown old in the service of his Lord that he received more communications from heaven than he had received during all the former years of his life. AA 572.2"
"They shall still bring forth fruit in old age; they shall be fat and flourishing;"
Both passages discuss the idea of bearing fruit or being useful in old age. EGW uses John's experience on Patmos as an example, while Psalm 92:14 is a general statement about the righteous continuing to flourish in old age.
