Pharoah has already allocated the land of Goshen to the family (Genesis 45:10). It has all been planned in advance where they will live.
Bishop Hall says, ‘The intermission of comforts hath this advantage, that it sweetens our delight more in the return, than was abated in the forbearance. God doth ofttimes hide away our Joseph for a time, that we may be more joyous and thankful in his recovery. This was the sincerest pleasure that ever Jacob had, which therefore God reserved for his old age.’ He then applies this to the wonderful reunion which the saints will experience in heaven when death in its cruelty has separated us for a time from those we loved most in this world, but which the resurrection has reunited again.
