Who was jachin

The name Jachin translates literally as "it shall be established" 1. Taken together with its companion pillar Boaz—meaning "in thee is strength"—it serves as a symbol of the strength and stability of the Masonic institution 1.

William Preston later expanded this symbolism within the lodge lectures, introducing a reference to the biblical pillars of cloud and fire 1. In this reading, the two pillars signify the Fraternity's absolute dependence on the superintending guidance and divine providence of the Great Architect of the Universe, by which that strength and stability are preserved 1.

In historical context, Jachin stood free-standing on the south side of the porchway entrance to King Solomon’s Temple, opposite Boaz on the north 1. While early interpretations focused purely on Hebrew translations, later scholarship noted that the name may also derive from a Phoenician verbal form meaning "He will be" 1. Because the pillars were crafted by Hiram Abiff, a Tyrian artist, they reflect the architectural traditions of Western Asia, where such detached columns served as conventional symbols of the sacred presence of Deity 1.
