I have trodden the winepress alone ... for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment. Isaiah 63:3
What made Joseph decide to take his family to Egypt?
An angel appeared to him in a dream and told him to.
The angel of the Lord appeareth to Joseph in a dream, saying, Arise, and take the young child and his mother,
and flee into Egypt, and be thou there until I bring thee word: for Herod will seek the young child to destroy him. Matthew 2:13
