When I was a little kid I read that cool book I posted as picture.
Thing is… I was a little kid a loooooong time ago, and remember very little of it.
I wanted to know WHO can bless… I believe the book defended that any authority can bless those under them (as in… not invoke God to bless, but bless directly, like when Isaac bless his sons, not like when people say "God bless you" when they are departing form each other)
