Isaiah 54:12

thy windows Rather as R.V. pinnacles. The word is derived from that for "sun," and appears to denote those parts of the building which glitter in the sun's rays. (Comp. the Arab. "minaret," used primarily of a lantern or a lighthouse.)

agates (Ezekiel 27:16) "sparkling" stone, perhaps rubies (so R.V.).

carbuncles (only here) "fiery" stones; although the LXX. renders "stones of crystal."

all thy borders R.V. border, perhaps the outer wall (the περίτειχος, see on ch. Isaiah 26:1).
