As 'brass' is a compound, it is probable that copper is the metal often alluded to in scripture. See Deuteronomy 8:9 . In some cases it may be 'bronze,' as it is known that this was in use in ancient Egypt. The Hebrew word nechosheth is translated 'copper' in Ezra 8:27 , where it is said to be 'precious as gold.' Brass is used as a symbol for righteousness according to the claims of God upon man, as in the brazen altar; the Lord as seen in the vision in the Revelation has feet like fine brass, 'burning as in a furnace:' that is, righteous judgement according to responsibility. Revelation 1:15; Revelation 2:18 .
