Joseph talked about his coming to Egypt?
(God planned, although his brothers' plan were evil
from men's point of view,God made it happened at
right time and right place, this event became a
very important and irreplacible spot on a big picture)

if you do,
it is very similar to understand the event of 法老把撒莱带进宫,

we can act as ZhuGe Liang afterwards
never forget God is always on the center.
