This word is sometimes used figuratively, to express power, durableness, and hardness. Thus in relation to Christ, John saith, when he saw him in that glorious vision, (Revelation 1:15) "his feet were like unto fine brass, as if burning in a furnace;" denoting the glory and everlasting nature of his person and kingdom. We read also of mountains of brass in reference to the everlasting establishment of JEHOVAH'S purposes, Zechariah 6:1. Sometimes the word brass is made use of to set forth the impudence of hardened sinners; "Thy neck is an iron sinew, and thy brow brass." (Isaiah 48:4) And sometimes the Lord gives some sweet and precious promises to his people under this figure, "Arise, and thresh, O daughter of Zion! for I will make thine horn iron, and I will make thy hoofs brass." (Micah 4:13)
