Kapparot was strongly opposed by some rabbis, their reasoning was based on the caution that it is similar to non-Jewish rites.
In many Egyptian Jewish families, about a week to ten days before Rosh Hashana, grains of wheat (or, if not readily available, barley or lentils) are scattered on a piece of damp cotton wool in a small plate or shallow bowl which sprout in time for the New Year. Early in the New Year, usually after Yom Kippur, the Day of Atonement, ten days later, the sprouts are discarded. I have not encountered reference to the practice of this custom in any other Jewish community other than that of or originating from Egypt.
They took place at the beginning of the fourth month of the Egyptian year, when the annual flooding of the Nile began to recede and the submerged fields began to re-emerge, ready to be sown. Small figurines in the form of Osiris were fashioned of moist clay and filled with grains, which were placed on a base. After a few days, the grains sprouted and a small growth appeared, the outline of which was in the shape of the clay figurine in which they had germinated (literally "which had given birth to them"). Thus, like its god, the soil of Egypt, after its annual death in the burning heat of summer, was reborn after the retreat of the floodwaters of the Nile, ready for a new growth of life. Do contemporary Egyptians, who still sow lentils on moist cotton wool to sprout for certain religious festivals, realize the ancient origins of this practice?
In the Responsa of the Geonim I have found that [in the days of the Sages of the Talmud] they made baskets from palm fronds and filled them with soil and dung and twenty-two or fifteen days before Rosh Hashana each and every one made one for each and every male and female child of the household and sowed in it Egyptian beans [ie cow peas] or pulses and it was called purpesa [parpisa] and it sprouted. And on the eve of Rosh Hashana everyone took his own and circled it around his head seven times saying: "This in lieu of this; this is my exchange; this is my substitute" and then threw it into the river.
