And again, because of my delighting in the house of my God, the substance I have -- a peculiar treasure of gold and silver -- I have given for the house of my God, even over and above all I have prepared for the house of the sanctuary:

For the LORD hath chosen Jacob unto himself, and Israel for his peculiar treasure.

I gathered me also silver and gold, and the peculiar treasure of kings and of the provinces: I gat me men singers and women singers, and the delights of the sons of men, as musical instruments, and that of all sorts.

And they shall be unto me a peculiar treasure, saith Jehovah of hosts, in the day that I prepare; and I will spare them as a man spareth his own son that serveth him.
