Мелахим А 7:21 Каббала: Sha'arei Orah

Know now, that corresponding to this Divine quality, King Solomon built the second pillar in the Holy Temple, and called its name Bo’az-בועז. That is, there were two pillars in the Holy Temple, called Yachin-יכין and Bo’az-בועז.⁸⁶Kings I 7:21 – “He erected the right pillar and called its name Yachin-יכין-established, and he erected the left pillar and called its name Bo’az-בועז-strength is in it.” (Yachin-יכין corresponds to the positive commandments and Bo’az-בועז corresponds to the negative commandments.) This matter is hinted at in the verse,⁸⁷Song of Songs 5:15 “His legs-Shokav-שוקיו are like marble pillars (Amudei Sheish-עמודי שש), founded (Meyusadim-מיוסדים) in sockets-Adnei-אדני of fine gold.” The word, “His legs-Shokav-שוקיו,” refers to these two qualities of victory-Netzach and majesty-Hod, which are the matter of HaShem God of Hosts-HaShem Elohi”m Tzva’ot-יהו״ה אלהי״ם צבאו״ת. They are the pillars that uphold the Sefirot, corresponding to which Solomon made the two pillars, Yachin-יכין and Bo’az-בועז.

Know, that corresponding to this quality of victory-Netzach-נצח, called HaShem of Hosts-HaShem Tzva’ot-יהו״ה צבאו״ת, King Solomon built the right pillar in the Holy Temple called by the name Yachin-יכין.²³¹Kings I 7:21 – “He erected the right pillar and called its name “Yachin-יכין-established,” and he erected the left pillar and called its name “Bo’az-בועז-strength is in it.” Whoever knows the secret of these two pillars, called Yachin-יכין and Bo’az-בועז, knows how the souls, called Neshamot, Ruchot, and Nefashot, burst forth through the qualities of the Living God-E”l Chai-א״ל חי, and the Lord-Adona”y-אדנ״י, by the influence of these two pillars.
