After the flood, G‑d promised Noah that He would never again bring a flood that would destroy the world. A rainbow is a reminder of this covenant that G‑d made with Noah, his descendants, and all living creatures. Therefore, upon seeing a rainbow in the sky, we recite the following blessing:
בָּרוּךְ אַתָּה ה' אֶלוֹהֵינוּ מֶלֶךְ הָעוֹלָם זוֹכֵר הַבְּרִית וְנֶאֱמָן בִּבְרִיתוֹ וְקַיָם בְּמַאֲמָרוֹ
Baruch ata Ado-nai Elo-heinu melech ha'olam zocher ha'brit v'ne'eman bivrito v'kayam b'ma'amaro.
Blessed are You, Lord our G‑d, King of the universe, who remembers the covenant, and is faithful to His covenant, and keeps His promise.
All the best,

can chabad.org make sure any time there is hebrew on their site it is the standard font that all jews know how to read as hebrew and not this modern hard to read font where the make letters look not the way letters actually look so therefore i can barely even read it because one of the letters is a straight line and in normal font it's not at all a straight line? just struggled to read this bracha. but wouldn't have if it were in normal classic font.
