Devarim 26:1-11 record the bikkurim ceremony that a farmer was to bring some of his new crops to the chosen place and make two declarations, 26:3 and 26:5 through the first half of 26:10, the mikra bikkurim. 26:4 records that after making the first declaration, 26:3, the farmer would give a basket of his new crops to the priest who would put it down by the altar. The farmer would then recite the second declaration, 26:5 through the first half of 26:10, and after finishing this declaration, the second half of 26:10 records that the basket would be put down before G-d. How could the basket be put down twice? Did the farmer pick up the basket when making the second declaration?
The Mishnah (Bikkurim 3:6) quotes two possibilities how the basket was put down during this ceremony. The first opinion, the anonymous tanna kamma, states that the farmer holds the basket on his shoulder the entire time he is reciting the second declaration, and after finishing the declaration he puts the basket down. This opinion seems to understand that the real placing down was at the end of the second declaration, and then the first placing down mentioned in 26:4 is understood to be on the farmer’s shoulders. As noted by David Hoffmann (1961, p. 486), it is hard to reconcile this approach with a simple reading of the Torah.
The second opinion, R. Yehuda, states that when the farmer recites the second declaration, he holds the edge of the basket while the priest holds the bottom of the basket. After the farmer finished reciting the verses, he then placed the basket down. Hoffmann writes that this approach accords with the Torah, but still 26:4 seems to state that only the priest is holding the basket at this point of the ceremony and the priest would place the basket down by the altar, while with R. Yehuda’s approach, the farmer is also holding the basket when making the second declaration and the basket is not placed by the altar prior to the second declaration.
My guess is that this double reference to putting the basket down is to indicate that two actions, the farmer’s declaration and the putting down of the basket, were happening concurrently. If the Torah had only recorded that the basket was to put down once, then one would have thought that it was to be put down either before the farmer started his second declaration (if only 26:4 was recorded) or that the placing was to be done after the farmer had finished his second declaration (if only the second half of 26:10 was recorded). However, with the double reference to putting down, we see that that the basket had to be put down both before and after the second declaration. How could this be?
The crucial point is that it would take some time (a minute? five minutes?) for the priest to take the basket from the farmer and put it down by the altar. This action would begin before the farmer made the second declaration and continue when the farmer was reciting the second declaration, as then the farmer would end the declaration or part of it before the basket was put down. Thus, prior to the farmer’s second declaration, he would hand the basket to the priest, who would then go to place it by the altar. The basket was not yet placed by the altar, but this is referred to as placing it down since once the farmer hands off the basket to the priest, the process of putting the basket down has begun. When the priest was walking over to the altar and putting the basket by the altar, the farmer would recite the verses of the second declaration and at this point he would not be holding the basket at all.
The first half of 26:10 records that the farmer ends the second declaration by stating that he has brought his crops since by finishing the second declaration and by having given his crops (in the basket) to the priest, he has fulfilled his obligation to bring the bikkurim. The second half of 26:10 then records that the basket is placed down before G-d, and this is referring to the action by the priest, who placed the basket down by the altar when the farmer was reciting the verses or depending on how long it took for the priest to place the basket down, after the farmer finished making the second declaration. The putting down in 26:10 is attributed to the farmer since the priest is the messenger of the farmer, but it is the priest who is putting the basket down (see Hoffmann, 1961, p. 486).
In conclusion, the double reference to putting down the basket during the bikkurim ceremony enclose the second declaration of the farmer, and signify that when the farmer was making his second declaration the priest was simultaneously putting down the basket by the altar.
