Leviticus 22:27 "And from the eighth day onward, it shall be acceptable as a sacrifice"

The Torah considers an animal younger than eight days old as inappropriate to be offered as a sacrifice.

We are commanded to sacrifice animals which are at least eight days old.

Deuteronomy 23:19 "You shall not bring the hire of a harlot or the price of a dog, into the house of the L-rd your G-d"

Animals that are designated to be offered as sacrifices must be acquired in a proper and dignified way.

This Negative Mitzvah cautions us not to offer an animal that has been obtained in a manner which the Torah considers improper or not becoming.

Leviticus 2:11 "For you shall burn no leaven, nor any honey, in any offering"

Besides animal sacrifices, meal offerings are also presented on the altar.

These offerings are made of wheat and oil, and they are called a "Minchah Offering".

The ingredients of the Minchah are mixed and formed into a dough.

This dough may not be leavened dough, which means it must not rise high like bread. (Just like on Pesach when we are forbidden any leavened dough, which is called Chametz.)

Also, a sweetener like honey, fruit juice or date extract may not be used, because it causes the dough to rise. We are forbidden to present dough that has risen as a meal offering upon the altar.

Leviticus 2:13 "With all your offerings you shall offer salt"

Salt is a very effective preserver.

The Torah commands us to offer salt with all sacrifices.

This salt hints, that by presenting our offerings to HaShem we are "preserving" our closeness to Him (see also Negative Mitzvah 99).

Leviticus 2:13 "Neither shall you omit salt the covenant of your G-d"

All sacrifices must be offered with salt (see Positive Mitzvah 62). We are not allowed to present a sacrifice or meal offering which does not contain salt.

The Torah calls the addition of salt to the sacrifice "the covenant of your G-d."

A covenant is a treaty or pact made between two parties.

The Torah uses salt to symbolize HaShem's covenant with the Jewish people.

Salt does not spoil and it retains taste for a very long time, so, too, HaShem's bond with the Jewish people will never be broken.
