We do not bring Bikkurim (first fruits) before Shavuot, and if they are [nonetheless] brought, we must wait until Shavuot arrives and [only then] recite the declaration [beginning with "My father was a wandering Aramean..." (Deut. 26:5-10)].

Rabban Shimon ben Gamaliel says, we do not bring first fruits from dates, except for the dates that [grow] in Jericho, and we do not recite [the declaration] except over the dry ones. Rabbi Shimon ben Elazar says, we bring valley pomegranates [as opposed to valley figs (see notes to Y. Bikkurim 1.3.7)] and recite [the declaration over them].
