And the Shelamim sacrifice is completeness, and peace for all. And a person that offers a shelamim spreads peace in the world. Yaakov is the one who makes peace, as we said, since he is the one for this [side] and this [side]. And the shelamim unifies the positive mitzvot and negative mitzvot, from this side and from this side. And because of this it is called shelamim [completeness]. And the secret of the word is that it is written 'And Yaakov was a TAM person' (Genesis 25:27): a complete person. Complete above and complete below. Another explanation [for Job 25:2]: "dominion" this is Michael. "Dread" this is Gavriel. This [angel, Michael] has its basis of water, this [angel, Gavriel] has the basis of fire. And the Holy One of Blessing makes peace between them, as it is written "He makes peace on His heights / among the high ones" (Job 25:2).
