Commentaire sur La Genèse 31:54

ויזבח יעקב זבח AND JACOB OFFERED A SACRIFICE — he slaughtered cattle for the feast

ויקרא לאחיו, of Lavan. There was no need to invite Lavan himself seeing he was like a father to Yaakov’s children.

ויזבח, he prepared a festive meal so that they would eat together before taking leave of each other. This was in honour of the covenant just concluded.

For his friends who were with Lavan. Here Rashi does not explain “his brethren” as “his sons” as he did on v. 46, “Yaakov said to his brethren,” because here he would not make a feast for his sons. [You might ask:] Why did Rashi not explain there as he does here? The answer is: There Yaakov issued a command and said, “Gather stones.” He would say so only to those under his authority. Therefore Rashi explained it there as “his sons.”

Jetzt bereitete Jaakob ein Mahl auf seinem Berge. Das אהיו kann wieder nichts anderes, als Labans Genossen bedeuten.

לאחיו HIS BRETHREN — those of his friends who were with Laban (cf Targum Jonathan)

לאחיו, Lavan and the men with him. Now that they had concluded a peace treaty they considered themselves all as brothers.

Food, in general, is called bread... Rashi is answering the question: Why does it not say, “To eat meat,” as he slaughtered animals for them?

לאכל לחם TO EAT BREAD — Any article of food is termed לחם bread, as (Daniel 5:1) “made a great feast (לחם רב)”, and (Jeremiah 11:19) “Let us destroy the tree with the fruit thereof (בלחמו)".
