הלכה אויף בראשית 28:12

Sour "Lemons" are forbidden by some when they are squeezed into an empty bowl, even if they will later be used for food, since in lands where many lemons grow, they are used to squeezing them for their juice, in order to prepare the drink known as 'Limonada', and they fill up barrels of juice for this purpose. Even though the blessed Shulchan Aruch allowed the squeezing of lemons, those who forbid it nowadays make sense, and therefore modern authorities forbid squeezing it into an empty vessel. However, one who wishes to prepare 'Limonada', which is a beverage made of squeezed lemons together with sugar and water, they should first put the sugar in a bowl and squeeze lemons over it, and only then pour over water. But do not put the water before the squeezing of the lemons. They have found a sign for this in the Torah (Genesis 28:12) "Behold, a ladder (sulam) standing on the earth". The word Sulam is the initials of the words Sugar, Lemon, Mayim (water), which is the order that the lemonade is to be made.

The matters concerning which a prophet is informed by vision of prophecy, are imparted to him allegorically, but the interpretation thereof is engraved upon his heart simultaneously with the vision and he knows what it means, as the vision of the ladder which Jacob our father saw: "The angels of God were ascending and descending upon it" (Gen. 28.12); which was a parable, the interpretation of which is the rise and fall of kingdoms, or as the Living Creatures which Ezekiel saw (Ezek. 1. 1–27), or the Seething Pot and the Almond Rod which Jeremiah saw (Jer. 1.12–13), or the Scroll of Parchment which Ezekiel saw (Ezek. 2.9), or the Measure which Zechariah saw (Zech. 2.5). And so with the rest of the prophets; some of them relate the parable and its interpretation as these; others relate the interpretation alone; and still others relate the parable only without the interpretation, as parts of the prophecies of Ezekiel and Zechariah, but all of them are prophesying in parables and metaphors.
