'Golden' in the Bible

I turned to see who it was that was speaking to me; and then I saw seven golden lampstands,

And when He had taken the book, the four living creatures and the twenty-four Elders fell down before the Lamb, having each of them a harp and bringing golden bowls full of incense, which represent the prayers of God's people.

And another angel came and stood close to the altar, carrying a censer of gold; and abundance of incense was given to him that he might place it with the prayers of all God's people upon the golden altar which was in front of the throne.

The sixth angel blew his trumpet; and I heard a single voice speaking from among the horns of the golden incense altar which is in the presence of God.
