And they shall be mine, saith the LORD of hosts, in that day when I make up my jewels; and I will spare them, as a man spareth his own son that serveth him. They shall be mine - I will acknowledge them as my subjects and followers; in the day, especially, when I come to punish the wicked and reward the righteous.
When I make up my jewels - סגלה segullah, my peculium, my proper treasure; that which is a man's own, and most prized by him. Not jewels; for in no part of the Bible does the word mean a gem or precious stone of any kind. The interpretations frequently given of the word in this verse, comparing saints to jewels, are forced and false.
I will spare them - When I come to visit the wicked, I will take care of them. I will act towards them as a tender father would act towards his most loving and obedient son.
