Mishnah — Seder Zeraim, Tractate Berakhot…
“ Bless upon the bad When an event is bad, even if it will ultimately turn out for the good, the appropriate blessing is the one for bad news. [For example, if a flood comes, even if it will enrich the soil] upon the good When an event is good, even if it will ultimately cause harm, the appropriate blessing is the one for good news. ”
