במדבר, פרק ז׳, פסוק מ״ח

As the dedication of the altar reaches its seventh day, the leader of the tribe of Ephraim steps forward to present his offering. The events of this day, along with the identity of the leader, are deeply intertwined with the legacy of the tribe's ancestor, Joseph, and the trials he faced in Egypt. A central question arises regarding the nature of this seventh day. While any twelve-day sequence of offerings must inevitably include a Sabbath [אבן עזרא], the primary approach among commentators is that this specific day of dedication fell exactly on the Sabbath itself. This creates a legal difficulty, as an individual's offering does not normally override Sabbath laws. To resolve this, commentators explain that the offering was permitted as a special, temporary ruling [רבנו בחיי, חזקוני]. Alternatively, the offerings of the tribal leaders were treated as communal offerings, which are permitted on the Sabbath, or the joy of the altar's dedication was considered a continuous festival that could not be interrupted [העמק דבר].

The unique privilege granted to the tribe of Ephraim to bring an offering on the Sabbath is rooted in the merits of their ancestors. God allowed this as a reward for Joseph, who upheld the prohibition against adultery even before the Torah was given [רבנו בחיי, שפתי כהן, צאינה וראינה], and who strictly observed the Sabbath and prepared special meals for it while living in Egypt [דעת זקנים, צאינה וראינה]. Another reason connects to Joshua, a descendant of Ephraim, who later conquered Jericho on the Sabbath by divine command and dedicated its spoils to God. Measure for measure, his tribe was permitted to override the Sabbath for this sacred offering [רבנו בחיי, דעת זקנים].

The sequence of the offerings is also highly deliberate. God ensured that the tribes of Joseph's two sons presented their offerings on consecutive days, the seventh and the eighth, without any other tribe interrupting them [רבנו בחיי, שפתי כהן]. Yet, despite this honor, Joseph's own name is noticeably absent from the mention of the tribe, contrasting with how he was listed during the earlier census of the Israelites. This omission reflects a punishment for a specific moment of silence: Joseph's life was shortened because he did not protest when his brothers referred to their father Jacob as "your servant" [צאינה וראינה].

The very identity of the tribal leader, Elishama son of Ammihud, serves as a profound reminder of Joseph's moral strength during his trial with the wife of his Egyptian master [אור החיים, רבנו בחיי, שפתי כהן]. His name signifies that Joseph listened to God—or to the guiding image of his father, which appeared to him like the Divine Presence—and refused to yield to the Egyptian woman's demands. His lineage further illustrates that his glory remained with God, as he rejected physical intimacy with wickedness. Ultimately, Joseph maintained a constant and unwavering reverence for God, whether he was an impoverished slave or a powerful ruler.
