And Abaye said: At first I would say that the reason for this practice that people do not sit under a gutter is because of the waste water that pours out of it. But the Master said to me that it is because demons are commonly found there.

There were certain porters who were carrying a barrel of wine. When they wanted to rest, they placed it under a gutter and it burst. They came before Mar bar Rav Ashi, who brought out horns and had them blown as he excommunicated the demon of that place. The demon came before Mar bar Rav Ashi, and the Sage said to it: Why did you do this? The demon said to him: How else should I act, when these men place a barrel on my ear?

Mar bar Rav Ashi said to it: What are you doing in a place where many people are found? You are the one who deviated from the norm; go and pay them the value of the barrel of wine. The demon said to him: Let the Master now set a time for me, so that I can find the money, and I will pay. Mar bar Rav Ashi set a time for his payment.

When that time arrived, the demon delayed. When it eventually came, Mar bar Rav Ashi said to it: Why did you not come at the time set for you? The demon said to him: Any item that is tied up, or sealed, or measured, or counted, we have no authority to take it. We are unable to obtain money until we find an ownerless item. For this reason, it took him a long time to find enough money to pay for the barrel.

The Sages taught: One who goes to measure the grain on his threshing floor recites: May it be Your will, O Lord, our God, that You send blessing upon the product of our hands. If one began to measure the grain he says: Blessed is He Who sends blessing upon this pile of grain. If one measured and afterward recited this blessing, this is a prayer made in vain, because blessing is found neither in a matter that is weighed, nor in a matter that is measured, nor in a matter that is counted. Rather, it is found in a matter concealed from the eye, as it is stated: “The Lord will command blessing with you in your storehouses.”

The Sages taught: Six statements were said with regard to demons: In three ways they are like ministering angels, and in three ways they are like humans. The baraita specifies: In three ways they are like ministering angels: They have wings like ministering angels; and they fly from one end of the world to the other like ministering angels; and they know what will be in the future like ministering angels.

And in three ways they are similar to humans: They eat and drink like humans; they multiply like humans; and they die like humans.

Six statements were said with regard to humans: In three ways, they are like ministering angels, and in three ways they are like animals. The baraita explains: In three ways they are like ministering angels: They have intelligence like ministering angels; and they walk upright like ministering angels; and they speak in the holy tongue like ministering angels. In three ways humans are like animals: They eat and drink like animals; and they multiply like animals; and they emit excrement like animals.

and that they may offer their sacrifices no more to the goat-demons after whom they stray. This shall be to them a law for all time, throughout the ages.

לשעירים .means TO THE DEMONS. Similar is (Isaiah 13:21) “and demons (ושעירים) shall dance there" (Sifra, Acharei Mot, Chapter 9 8).

... The three things in which they are comparable to human beings are that they eat and drink, procreate, and die as do human beings.” Now the cause of death generally is the separation [decomposition] of the components of the body, this being true of all kinds of bodies [whether they are composed of the four elements like humans or of only two, like sheidim]. The reason for their ability to fly is because of the lightness of the [two] elements [fire and air] of which they are composed, as may also be seen in the case of a fowl, in which, because the elements of fire and air dominate over the small parts of the other two elements [earth and water], the fowl can hover in the air and fly [although it is composed of all four elements]. Surely, then, the above-mentioned creatures that have nothing in them of the heavy elements [earth and water], possess great hovering power in the air, to be able to fly tirelessly. The matter of “eating” [mentioned above in connection with these creatures] means their deriving nourishment from the moisture of water and the odors of fire, something like the fire that licked up the water that was in the trench. This is the purpose of the burnings which necromancers perform to the demons...

...Therefore Onkelos rendered the verse, They sacrificed unto demons, ‘lo eloha’ (no gods), as “they sacrificed unto demons in which there is no utility,” meaning that there is no need for them, as they do not prevent harm that is destined to come, neither do they do anything productive, nor do they inform of times far off so that a person may knowingly guard himself. It is this which is the sense of the expression, lo eloha, which is as if it said, “no power or rulership,” for the word Elokim is an expression of strength and power, [a composite word consisting of the words] e-il heim. Thus the verse is stating that demons have no strength or power whatsoever, and hence there is no need for them, for they cannot do evil, neither is it in them to do good.

They are like a scarecrow in a cucumber patch, they cannot speak. They have to be carried, for they cannot walk. Be not afraid of them, for they can do no harm; Nor is it in them to do any good.
