Genesis 42:7-9 “And Joseph recognised ..and remembered the dreams which he had dreamed about them”.  Josephs’ dream in Genesis 37 was about the bundles of grain bowing down.  So even the grains had meaning.  Sometimes we just don’t see the whole picture, but with YHVH every little thing has meaning and purpose.  And those things only become clear for us later.  Even with Yeshua, He explained so much to His disciples.  But only after when He went up to Heaven, suddenly a lot of things started to make sense with them.  They started connecting the dots, with prophecies from hundreds to thousands of years given before.
