Myśl Żydowska do Kapłańska 2:13

And the Rabbi of the Guide wrote in Part 3, Chapter 46 (Guide for the Perplexed 3:46): As most could not afford to offer a beast, the [Torah] commanded that birds also should be sacrificed. [...] Those who are too poor to offer a bird, may bring bread of any of the kinds then in use: baked in the oven, baked in a pan, or in a frying-pan. If the baking of the bread is too much trouble for a person, he may bring flour. [...] The idolaters did not offer any other bread but leavened, and chose sweet things for their sacrifices, which they seasoned with honey, as is fully described in their books: but salt was not brought in any of their sacrifices. God, may He be elevated, therefore forbade us to offer leaven or honey, and commanded us to have salt in every sacrifice - "with all your offerings shall you then offer salt" (Leviticus 2:13). And he wrote further: When the sacrifice is of flour, it is soaked in oil; for that is what is best and pleasant. And the frankincense was chosen because of the goodness of the smell of its smoke in its place, in which the meat is burnt. To here are his [words].

The idolaters did not offer any other bread but leavened, and chose sweet things for their sacrifices, which they seasoned with honey, as is fully described in the books which I named before: but salt is not mentioned in any of their sacrifices. Our Law therefore forbade us to offer leaven or honey, and commanded us to have salt in every sacrifice: “With all thine offerings thou shalt offer salt” (Lev. 2:13).
