Berachos 9:1 - 9:2

מקום שנעשו בו נסים – such as the place where the Israelites crossed the Sea of Reeds and the stream of Arnon (see Numbers, chapter 21, verses 13 and following), and the fords of the Jordan River [where the Israelites crossed – see Joshua, chapter 3 verse 14 and following] the stone on which Moses, of blessed memory, sat when he fought the war against Amalek (see Exodus chapter 17, verse 12) and other similar occurrences. And public miracles such as these require everyone to recite a blessing, but individual miracles such as person who sees a place where a [personal] miracle had occurred for him, he himself is obligated to recite a blessing, “Praised [Are You, O LORD] who performed for a miracle in this bless,” and his son and grandson are obligated to recite the blessing, “Praised [Are You, O LORD] who performed a miracle for my ancestors in this place.” And all these blessings of our Mishnah require the mention of the Name of God and His Sovereignty – for any blessing which lacks the mention of God’s name and His sovereignty is not a blessing.

זיקין – A star that appears like it opens up the firmament and shoots like an arrow from place to place. Alternatively, it is a star that appears like it has a long tail.

זועות – That the earth quakes and trembles.

רעמים – Sound is that heard in the firmament from clouds that pour forth water from one to another, as it says (Jeremiah 51:16), “When He makes His voice heard, There is a rumbling of waters in the skies.”

ועל הרוחות – that come in a storm-wind in vehemence and are not found other than occasionally.

ברוך שכחו מלא עולם – And if he desires, he should recite the blessing, “Praised [are You God] who is the Author of Creation” for all of these are acts of creation as it is written (Psalms 135:7), “[He makes clouds rise from the end of the earth;] He makes lightning for the rain ; [He releases the wind from His vaults],”but on the mountains and on the hills, etc., one says, “Who is the Author of Creation, specifically, but he is not able to make the blessing on them, “that His power fills the world” which are not seen in most of the world, but rather each and every person [recites the blessing] in his place.

הים הגדול – The Mediterranean Sea that surrounds the world (at least as the ancients understood it).

ברוך שעשה הים הגדול – On account of its size and importance, establishes a blessing for itself.

לפרקים – At thirty day intervals

על הגשמים – He recites the blessing, “Who Is Good and Does Good” as whomever possesses land in partnership with another, for this is implies "הטוב והמטיב"/Who is Good and Does Good”; – Good – for himself and “who does good”- for another; but he who lacks land altogether should say, “We give thanks to You, O LORD our God for every drop [of rain] that you have caused to fall for us, etc.” And if he owns land on his own, he makes the blessing, “שהחיינו/Who has Kept Us Alive.”
