Benaiah (, "Yahweh builds up") is a common name in the Hebrew Bible.
In the etymology of the name, the first part of Benaiah comes from the root-verb ÃÂÃÂ ÃÂ (bana), which is a common Hebrew verb meaning "to build". The second part of Benaiah is ÃÂÃÂ (Yah), which is not a derivative of the Tetragrammaton, but a contraction of it (ie, the first and last consonants of ÃÂÃÂÃÂÃÂ are contracted as ÃÂÃÂ).
The most famous Benaiah referenced in the Tanakh is the son of Jehoiada, who came from the southern Judean town of Kabzeel.
According to the text, Benaiah was one of David's Mighty Warriors, commander of the third rotational army division; (; ). He helped David's son Solomon become king, killed Solomon's enemies, and served as the chief of Solomon's army. On Solomon's instructions he was responsible for the deaths of Adonijah (), Joab () and Shimei (). He was in charge of the Cherethites and Pelethites. Several verses in illustrate Benaiah's close association with Solomon's party and his exclusion from Adonijah's faction. He is also mentioned in , , and .
According to Rabbi Hayyim Vital, the grave of Benaiah is in Biriya. In 1869, Rabbi Yosef Hayyim of Baghdad visited the grave and stayed there for a few days. In the introduction to his book, "Ben Ish Chai", he wrote that "many and great secrets" were revealed to him there, and even that "his soul came from the soul of Baniahu ben Yehoida," and that is why he named his books after him.
