Netzach (Hebrew: נצח, “victory”) is the seventh of the ten Sefirot in the Jewish mystical system of Kabbalah. It is located beneath Chesed (‘loving-kindness’), at the base of the “Pillar of Mercy” which also consists of Chochmah (‘wisdom’). Netzach generally translates to ‘eternity’, and in the context of Kabbalah refers to ‘perpetuity’, ‘victory’, or ‘endurance’.
Ancient Israelite explanation
Netzach (Hebrew נצח) communicates the idea of long-suffering, strength, endurance unto completion or patience. This term appears eight times in the Hebrew scriptures and derivatives of this child root נצח from the parent root נח appear over forty times in the Hebrew text. See the following passages:
- 1 Samuel 15:29 וְגַם֙ נֵ֣צַח יִשְׂרָאֵ֔ל לֹ֥א
Also the strength (נצח) of Israel will not….
- Job 34:36 אִיּ֣וֹב עַד־ נֶ֑צַח עַל־ תְּ֝שֻׁבֹ֗ת
I request [that] Job will be proven up to the limit (נצח); he will return above men of misfortune.
- Psalms 13:1 יְ֭הוָה תִּשְׁכָּחֵ֣נִי נֶ֑צַח עַד־ אָ֓נָה
Yahweh, will You forget me continually (נצח)? Until when?
- Jeremiah 15:18a הָיָ֤ה כְאֵבִי֙ נֶ֔צַח וּמַכָּתִ֖י אֲנוּשָׁ֑ה֙
Why has my suffering been without end (נצח)?
- Amos 1:11c וְעֶבְרָת֖וֹ שְׁמָ֥רָה נֶֽצַח׃
and he nursed his grudge forever(נצח).
