When Semyaza stole the Fruits of Wisdom from Heaven, God ordered the Flood on Earth.
When Enoch opposed His plan, God then ordered Enoch to bring back the souls of the Grigori, so that the Flood be averted.
Trivia
Rumors say that God picks his teeth with an Arch[1]. But not likely to be literal, as God does not resemble a human being.
