Positive Commandment 150 (Digest)
Inspecting Birds for Kosher Signs

"You may eat all clean birds"Deuteronomy 14:11.

We are commanded to inspect fowl before consuming them, to ascertain whether they possess the signs that characterize non-kosher birds. The Torah doesn't specify signs for non-kosher fowl; rather, it supplies us with a list of forbidden fowl species. Nevertheless, when studying the group of the listed birds, we can isolate certain common signs that they all share.

Positive Commandment 151 (Digest)
Inspecting Grasshoppers for Kosher Signs

"Yet these you may eat of every flying creeping thing"Leviticus 11:21.

We are commanded to inspect grasshoppers before consuming them, to ascertain whether they possess the kosher sign: "jointed [leg like] extensions above their [regular] legs."

Positive Commandment 152 (Digest)
Inspecting Fish for Kosher Signs

"These you shall eat of all that is in the water"—Leviticus 11:9.

We are commanded to inspect fish before consuming them, to ascertain whether they possess the kosher signs [—fins and scales].

Negative Commandment 172 (Digest)
Non-Kosher Mammals

"These you shall not eat of those that [only] chew the cud or of those that [only] have the cloven hoof..."Deuteronomy 14:7.

It is forbidden to eat any mammal that doesn't possess both kosher signs—split hooves and chewing cud.

Negative Commandment 174 (Digest)
Non-Kosher Birds

"And these you shall detest among the birds, they shall not be eaten"—Leviticus 11:13.

It is forbidden to eat any non-kosher bird.

Daily Quote
Ten things were created at twilight of Shabbat eve: the mouth of the earth [that swallowed Korach]; the mouth of [Miriam's] well; the mouth of [Balaam's] ass; the rainbow; the manna; [Moses'] staff; the shamir; the writing, the inscription and the tablets [of the Ten Commandments]. Some say also the burial place of Moses and the ram of our father Abraham. And some say also the spirits of destruction as well as the original tongs, for tongs are made with tongs
