“Gold and a multitude of gems, etc. This is the boast of the wise buyer, who, as long as he buys, says that what happens to him is bad: but when someone has hurt or offended the saints of God, and has not refrained from treating them like a vile servant according to his own pleasure, he will rejoice that he has wisely made his purchase. Likewise, the buyer of the heavenly kingdom will rejoice when he departs from here, finding that the lips of knowledge, that is, of spiritual doctrine, used in the acquiring of heavenly things, are to be compared to gold, gems, and precious vessels.”
