וישאהו במוט בשנים ומן הרמנים ומן התאנים (שלח יג:כג)

The Ari Hakadosh zt’’l writes that the Mitzvah of Bikurim serves as an atonement for the sin of the Meraglim. Since it says by Bikurim that when a Yid sees in his field a fig, a strand of grapes, or a ripe pomegranate, he ties a rubber around it and brings it to the Beis Hamikdash as Bikurim.  The Mishnah specifically mentions these three fruits because the Meraglim brought them from Eretz Yisroel – and the mitzvah of Bikurim serves as an atonement.
