THEREFORE WE WILL SAY THEM BOTH. Rav Popo says that since two feasible phrases were suggested for this b’rochoh to be said upon seeing a rainbow, we should recite both.R’I says that we do not say a conclusion for this b’rochoh. And how do we recite it? Blessed are you Hashem our G-d, King of the universe who is trustworthy in his covenant, and fulfills his promise and remembers his covenant.

RAVA SAID: THERE, ONE RECITES: BLESSED…WHOSE POWER FILLS THE WORLD, AND: AUTHOR OF CREATION. **The explanation: he says this one, “**His power and might fill the world” **or that one, “**Who makes the works of creation”, **whichever he wants,**not both, and so did Rav Alfas explainRovo’s opinion.
