Court of the Women in Herod's Temple ISBE

The eastern gate, approached from the outside by 12 steps (Mid., ii.3; Maimonides), admitted into the court of the women, so called because it was accessible to women as well as to men. Above its single colonnades were galleries reserved for the use of women. Its dimensions are given in the Mishna as 135 cubits square (Mid., ii.5), but this need not be precise. At its four corners were large roofless rooms for storage and other purposes. Near the pillars of the colonnades were 13 trumpet-shaped boxes for receiving the money-offerings of the people (compare the incident of the widow's mite, Mk 12:41 ff; Lk 21:1 ff); for which reason, and because this court seems to have been the place of deposit of the temple-treasures generally, it bore the name "treasury" (gazophulakion, Jn 8:20).
