Isaiah 60:17

17. In the first part of Isaiah 60:17, the material of which the city is built is the allegorical subject.

For brass I will bring gold… for iron… silver… for wood brass… for stones iron In Solomon’s day (1 Kings 10:21; 1 Kings 10:27) civilization so rapidly advanced that in the above terms it was made a type, as here used, of advancing improvements evermore in Zion’s city. Gold in place of brass, silver in place of iron, etc., signify ever-growing preciousness in all that pertains to the temple of holy Zion. Compare Revelation 21:10-21.

Thy officers peace Better, Thy magistracy shall be peace. The term characterizing it shall be “peace;” shall be, in other words, order, truth, love. These shall mark the whole of Zion’s government.

Thy exactors Not tyrants or tyranny, but justice, equity absolute.
