The shut-up gold (1 Kings vi. 12) was of the purest and rarest
quality, so that when it appeared in the market for sale, all
shops in the locality were "shut up," for there could be no sale
of any other gold before that. All gold-dealers "shut up" their
shops in order to be present on so rare an occasion; and hence
the name of this kind of gold--"shut-up gold."
Each day of the Feast of Tabernacles they walked round the altar once,
and said, "O Lord, save us, we beseech Thee! O Lord, prosper us, we
beseech Thee!" But on the last day they encompassed it seven times. On
their departure they said, "Beauty belongeth to thee, O altar! Beauty
belongeth to thee, O altar!"
