“The Lord will open for you His good storehouse, the heavens, to provide the rain of your land at its time, and to bless all your handiwork; you will lend to many nations, but you will not borrow” (Deuteronomy 28:12). “The Lord will open for you His good storehouse” – what is “will open [yiftaḥ]”? Rabbi Yonatan said: There are three keys [mafteḥot] in the hand of the Holy One blessed be He, and no creature has control over them, neither an angel nor a seraph, and these are: the key of the revival of the dead, the key of barrenness, and the key of rain.
The key of the revival of the dead, from where is it derived? It is as it is stated: “You will know that I am the Lord when I open your graves” (Ezekiel 37:13). The key of barrenness, from where is it derived? It is as it is stated: “[The Lord]…opened her womb” (Genesis 29:31).
The key of rain, from where is it derived? It is as it is stated: “The Lord will open for you His good storehouse.” Another matter: “The Lord will open for you” – the Rabbis said: Great is rainfall, as it is equivalent to the revival of the dead. It is as it is stated: “He will come to us like the rain, like the late rain that satiates the earth” (Hosea 6:3).
What is written thereafter?14Meaning, in another verse. In this case it is referring to the previous verse. “He will revive us after two days” (Hosea 6:2). That is why they inserted it15The mention of rain. in the Revival of the Dead,16This is the second blessing of the Amida prayer. because it is its equivalent.
Another matter: “The Lord will open for you” – Rabbi Eliezer ben Yaakov said: When rain falls, business is also blessed, as it is stated: “To provide the rain of your land at its time, and to bless all your handiwork.” Our Rabbis said: The fish are also blessed. The Rabbis said: There was an incident where they caught a certain fish in Akko before rain fell, and they estimated its weight at three hundred litra; but they found that it weighed only two hundred.
A certain elderly man said to them: ‘Had rain fallen, they would have found that it weighed more.’ When rain fell, they caught a certain fish that they estimated its weight as two hundred litra, and they found that it weighed three hundred. That is, the fish are also blessed. Another matter: “The Lord will open for you” – see how great is rainfall.
Rav Yehuda bar Yeḥezkel, when he would see the rain falling, he would recite the blessing: May the name of the One who spoke and the world came into being be glorified, exalted, and blessed, as He appoints thousands of thousands and myriads of myriads of angels over each and every drop that falls. Why? It is because from here until the heavens is a walking distance of five hundred years, and rain falls and no drop intermingles with another.
Another matter: Great is the rainfall, as it is the equivalent of the revival of the dead. How so? “Opening [petaḥ]” is written regarding this, and “opening” is written regarding that. “Hand [yad]” is written regarding this, and “hand” is written regarding that.
“Song” is written regarding this, and “song” is written regarding that. Regarding the revival of the dead, it is written: “When I open [befitḥi] your graves” (Ezekiel 37:13). Regarding rainfall it is written: “The Lord will open [yiftaḥ] for you.” Regarding the revival of the dead, it is written: “The hand [yad] of the Lord was upon me” (Ezekiel 37:1).17This verse is an introduction to the prophecy that describes revival of the dead.
Regarding rainfall it is written: “You open Your hand [yadekha]” (Psalms 145:16).18This verse discusses sustenance, which is related to rain. Regarding the revival of the dead, it is written: “Rock dwellers will sing” (Isaiah 42:11).19According to Targum Yonatan, the verse refers to the revival of the dead. Regarding rainfall it is written: “They shout for joy, and they sing” (Psalms 65:14).20Verse 11 in this chapter mentions rain.
