The Septuagint in the parallel passage (margin reference), translate Jachin and Boaz by Κατόρθωσις Katorthōsis and Ἰσχύς Ischus - “Direction” and “Strength.” The literal meaning of the names is given in the margin. The meaning was probably “God will establish in strength” (i. e. firmly) the temple and the religion connected with it.
