The Lord spoke to Haggai on the 7th day of Tabernacles, which is the mirror image of the 7th day of Unleavened Bread, that the silver and gold are HIS. This was a reminder of the 7th day of Unleavened Bread when Joshua and the Israelites defeated Jericho and the Lord was adamant that all the silver and gold belonged to HIM. One man, took some gold and kept it for himself and it cost him his life. In Zechariah 6, we see that the silver and gold make the crowns that are set upon the head of Christ. And 2 Timothy explains (just after Paul mentions the resurrection of Christ and being chained, or imprisoned, both references to the Feast of Firstfruits) that the silver and gold represent those who are instruments for special purposes, made holy, useful to the Master and prepared to do any good work.

WE ARE THE SILVER AND THE GOLD. We belong to Christ. He is building His temple, His body, made of the chosen silver and gold, those who have been made holy and are prepared to do any good work. When was the silver and gold put into the treasury of the Lord? On the 7th day of Unleavened Bread, when the walls of Jericho fell.

Haggai 2:

On the twenty-first day of the seventh month, the word of the Lord came through the prophet Haggai: “Speak to Zerubbabel son of Shealtiel, governor of Judah, to Joshua son of Jozadak, the high priest, and to the remnant of the people. Ask them, ‘Who of you is left who saw this house in its former glory? How does it look to you now? Does it not seem to you like nothing? But now be strong, Zerubbabel,’ declares the Lord. ‘Be strong, Joshua son of Jozadak, the high priest. Be strong, all you people of the land,’ declares the Lord, ‘and work. For I am with you,’ declares the Lord Almighty. ‘This is what I covenanted with you when you came out of Egypt. And my Spirit remains among you. Do not fear.’

“This is what the Lord Almighty says: ‘In a little while I will once more shake the heavens and the earth, the sea and the dry land. I will shake all nations, and what is desired by all nations will come, and I will fill this house with glory,’ says the Lord Almighty. ‘The silver is mine and the gold is mine,’ declares the Lord Almighty.

Joshua 6:
On the seventh day, they got up at daybreak and marched around the city seven times in the same manner, except that on that day they circled the city seven times. The seventh time around, when the priests sounded the trumpet blast, Joshua commanded the army, “Shout! For the Lord has given you the city! The city and all that is in it are to be devoted to the Lord. Only Rahab the prostitute and all who are with her in her house shall be spared, because she hid the spies we sent. But keep away from the devoted things, so that you will not bring about your own destruction by taking any of them. Otherwise you will make the camp of Israel liable to destruction and bring trouble on it. All the silver and gold and the articles of bronze and iron are sacred to the Lord and must go into his treasury.”

Then they burned the whole city and everything in it, but they put the silver and gold and the articles of bronze and iron into the treasury of the Lord’s house.

Joshua 7: Achan replied, “It is true! I have sinned against the Lord, the God of Israel. This is what I have done: When I saw in the plunder a beautiful robe from Babylonia, two hundred shekels of silver and a bar of gold weighing fifty shekels, I coveted them and took them. They are hidden in the ground inside my tent, with the silver underneath.”

Zecheriah 6:
I looked up again, and there before me were four chariots coming out from between two mountains—mountains of bronze. The first chariot had red horses, the second black, the third white, and the fourth dappled—all of them powerful. I asked the angel who was speaking to me, “What are these, my lord?”

The angel answered me, “These are the four spirits of heaven, going out from standing in the presence of the Lord of the whole world. The one with the black horses is going toward the north country, the one with the white horses toward the west, and the one with the dappled horses toward the south.”

When the powerful horses went out, they were straining to go throughout the earth. And he said, “Go throughout the earth!” So they went throughout the earth.

Then he called to me, “Look, those going toward the north country have given my Spirit rest in the land of the north.”

The word of the Lord came to me: “Take silver and gold from the exiles Heldai, Tobijah and Jedaiah, who have arrived from Babylon. Go the same day to the house of Josiah son of Zephaniah. Take the silver and gold and make a crown, and set it on the head of the high priest, Joshua son of Jozadak. Tell him this is what the Lord Almighty says: ‘Here is the man whose name is the Branch, and he will branch out from his place and build the temple of the Lord. It is he who will build the temple of the Lord, and he will be clothed with majesty and will sit and rule on his throne. And he will be a priest on his throne. And there will be harmony between the two.’ The crown will be given to Heldai, Tobijah, Jedaiah and Hen son of Zephaniah as a memorial in the temple of the Lord. Those who are far away will come and help to build the temple of the Lord, and you will know that the Lord Almighty has sent me to you. This will happen if you diligently obey the Lord your God.”

Revelation 19:12
His eyes were as a flame of fire, and on His head were many crowns; and He had a name written, that no man knew, but He Himself.

2 Timothy 2:
Remember Jesus Christ, raised from the dead, descended from David. This is my gospel, for which I am suffering even to the point of being chained like a criminal. But God’s word is not chained... In a large house there are articles not only of gold and silver, but also of wood and clay; some are for special purposes and some for common use. Those who cleanse themselves from the latter will be instruments for special purposes, made holy, useful to the Master and prepared to do any good work.
