In the second last scene of episode 5x03 of Mad Men, Michael Ginsberg (one of the Jewish characters on the show) comes back home from the grocer's to be greeted by his dad. The latter encourages Michael to
get girls; an old one and a young one.
and ends up uttering/singing what appears to be a prayer/chant while facing Michael and cupping the latter's head.
I can't understand that bit, because I know no Hebrew. What is Michael's dad saying at that moment? Is it related to his son being single or not enjoying life enough?
