Netzach, victory, but also eternity, perseverance, is the seventh Sefirah, at the bottom of the right column. Elijah names it, together with Hod, "the two legs": what carries the body and moves it forward. The Pardes explains the name: "the seventh measure from top to bottom is called Netzach, because it is the measure of the world's victory"; it is sometimes called "Netzach Netzachim," victory of victories, and "Netzach Israel" when it is attached to the trunk. Samuel uses this name: "the Eternity of Israel does not lie." Netzach is the kindness that holds over time, Chesed that does not tire.
It is the fourth in the verse of Chronicles: "and the victory." Rabbi Akiva reads: "the victory, this is Jerusalem"; Rabbi Shila: "the fall of Rome." What lasts against what passes.
Netzach and Hod are inseparable; the Pardes calls them "the prophets of truth" and Cordovero's Ohr Ne'erav sums up: "prophets: Netzach and Hod." Prophecy passes through these two legs before reaching Malkhut, which receives it. This is why the tradition of the Zohar associates Netzach with Moses and Hod with Aaron, the two brothers, the prophet and the priest, the word and the service. The commentary Ohr HaChammah on the Zohar puts it in one line: "the patriarchs, Chesed, Gevurah, Tiferet; Moses and Aaron, Netzach and Hod." Note that Cordovero, in the Pardes, also makes Moses the chariot of Tiferet in the aspect of the hidden Da'at: Jacob is its body, Moses its soul.
The Tomer Devorah treats Netzach, Hod and Yesod in a single chapter, and it begins with what they have in common. "First, one must help those who study the Torah and support them, with one's money or with one's action," provide them with what they need, food, books, a house of study, "so that they are not turned away from words of Torah"; and take care not to disparage their study, but "honor them and praise their good deeds so that they grow stronger in the service." "Everything depends on these two qualities," he concludes, "each according to his strength." Then a second rule: the one who studies must "learn from every person," for "the Torah is not completed with a single teacher"; the one who makes himself a disciple of all becomes a chariot for Netzach and Hod.
What is proper to Netzach: "when he studies Scripture, which is of the right side, he has a particular relation to Netzach." The Mishnah, on the left side, is Hod; the Gemara, which links the two, repairs them together.
Keep the measure of Moses and of Netzach: to carry others over time. To support a student of Torah, to fund a house of study, is to walk with the right leg of the world.
