"Speak to Aaron and his sons: Thus shall you bless the people of Israel and say to them" that "The LORD bless you and protect you" - those who give a tithe to the priest and a tithe to the poor. "Bless you" by channeling great wealth to you. This indicates that the wealthy are like funnels into which the heavens pour generously, in order that they fill empty vessels – the poor on earth below. Should there be any obstruction below that prevents channeling plenty to the poor, the heavens will no longer pour forth, but should the hand be open – it being the bottom aperture – the channel that funnels plenty rushing down from above will even be widened.
