In scriptural language a wall is a symbol of salvation (Isaiah 26:1; Isa, Isaiah 60:18 ), of the protection of God (Zechariah 2:5 ), of those who afford protection (1 Samuel 25:16; Isaiah 2:15 ), and of wealth of the rich in their own conceit (Proverbs 18:11 ). A “brazen wall” is symbolic of prophets and their testimony against the wicked (Jeremiah 15:20 ). The “wall of partition” (Ephesians 2:14 ) represented Temple worship and Jewish practice separating Jew from Gentile.
