מִ֭נַּחַל בַּדֶּ֣רֶךְ יִשְׁתֶּ֑ה עַל־כֵּ֝֗ן יָרִ֥ים רֹֽאשׁ׃
Il boira sur la route de l’eau du torrent: aussi portera-t-il haut la tête.
Sifra
1) I might think that even a gourd which fell into the atmosphere of the oven and was not predisposed (to the acquisition of tumah) would become tamei; it is, therefore, written (Vayikra 11:34) "upon which water came." This tells me only of water (as a predisposing element). Whence do I derive the same for dew, wine, oil, blood, honey and milk? From "drink" — this is wine; "that is drunk" — this is blood, as it is written (Tehillim 110:7): "From a river, on the way, shall he drink (blood), wherefore he shall lift (his) head." Whence are other liquids derived (as predisposing elements)? From "and every drink." If "every drink," I would think (even) mulberry juice, fruit-juice, pomegranate juice, and (the juice of) all other kinds of fruits. It is, therefore, written "water." Just as "water" is characterized by the absence of a qualifying epithet, so I include dew, wine, oil, blood, honey, and milk, which have no qualifying epithets, and I exclude mulberry juice, pomegranate juice, and (the juice of) all other kinds of fruits, which have qualifying epithets.

4) "which shall be drunk": to exclude foul drink. These are the words of R. Eliezer. They said to him: No drink is out of bounds for birds or cows, (so that foul drink, too, predisposes to tumah).
Midrash Tehillim
I will praise the Lord with all my heart. As it is written (Isaiah 30:26), "And the light of the moon will be like the light of the sun, and the light of the sun will be sevenfold, like the light of the seven days, on the day that the Lord binds up the injuries of His people, and heals the wounds inflicted by His blow." This refers to the time when the Tower of Babel fell, which was caused by the wicked who prevent the light from shining in the world. It is also said (Judges 5:31), "Thus let all your enemies perish, O Lord!" At that time (ibid.), "And those who love Him are like the rising of the sun in its might." And at that time, God heals the brokenness of His people, as it is said (Isaiah 30:26), "On the day that the Lord binds up the injuries of His people." (Joel 4:14) "Multitudes, multitudes in the valley of decision." What is the valley of decision? It is a place where the judgment of those who fall there is final. As it is said (Jeremiah 25:33), "And the slain of the Lord shall be on that day from one end of the earth to the other end of the earth." (Until now they did not know.) (Psalm 110:6) "He will judge among the nations, He will fill them with corpses, He will crush the heads of many over the wide earth." In the future, rivers of blood will flow from the wicked, and the birds will come to drink from the stream of blood, as it is said (ibid. 7), "He will drink from the brook on the way." And the stream creates waves, and the wave comes to wash it away, and it lifts its head, as it is said (ibid.), "Therefore He will lift up His head." David said, "Praise and thanks I give for this." Therefore, we say Hallelujah.
