where does the saying bless you come from
God bless you The phrase has been used in the Hebrew Bible by Jews (cf. Numbers 6:24), and by Christians, since the time of the early Church as a benediction, as well as a means of bidding a person Godspeed.[4][5] Many clergy, when blessing their congregants individually or as a group, use the phrase "God bless you".[6]
Responses to sneezing In English-speaking countries, the common verbal response to another person's sneeze is "bless you", or, less commonly in the United States and Canada, "Gesundheit", the German word for health (and the response to sneezing in German-speaking countries). There are several proposed bless-you origins for use in the context of sneezing.
