In the New Testament, however, there are numerous references to the estimation in which pearls were held. In his teachings, Christ repeatedly referred to them as typifying something most precious: “The kingdom of heaven is like unto a merchant man, seeking goodly pearls: who, when he had found one pearl of great price, went and sold all that he had, and bought it” (Matt. xiii. 45, 46); and in “casting pearls before swine,” in that great Sermon on the Mount (Matt. vii. 6). In picturing the glories of the Heavenly City, St. John made the twelve gates of pearls (Rev. xxi. 21); and what could better serve as portals through the walls of precious stones? In the Talmud, pearls are frequently mentioned, and usually as signifying something beautiful or very costly, as “a pearl that is worth thousands of zuzim” (Baba Batra, 146a); a “pearl that has no price” (Yerushalmi, ix. 12d); the coats which God made for Adam and Eve were “as beautiful as pearls” (Gen. R. xx. 12), and the manna was “as white as a pearl” (Yoma, 75a). Their purchase formed one of the exceptions to the law of _Ona’ah_ (overcharge), for the reason that two matched pearls greatly exceeded the value of each one separately (Baba Mezi’a, iv. 8). The high value attached to pearls by the ancient Hebrews is illustrated by a beautiful Rabbinical story in which only one object in nature is ranked above them. On approaching Egypt, Abraham hid Sarah in a chest, that foreign eyes might not behold her beauty. When he reached the place for paying custom dues, the collectors said, “Pay us the custom”; and he replied, “I will pay your custom.” They said to him, “Thou carriest clothes”; and he stated, “I will pay for clothes.” Then they said to him, “Thou carriest gold”; and he answered, “I will pay for gold.” On this they said to him, “Surely thou bearest the finest silk”; and he replied, “I will pay custom for the finest silk.” Then said they, “Truly it must be pearls that thou takest with thee”; and he answered, “I will pay for pearls.” Seeing that they could name nothing of value for which the patriarch was not willing to pay custom, they said, “It cannot be but that thou open the box and let us see what is within.” So the chest was opened, and the land was illumined by the luster of Sarah’s beauty.[7] The love which the early Arabs bore to pearls is evidenced by the references to them in the Koran, and especially the figurative description given of Paradise. The stones are pearls and jacinths; the fruits of the trees are pearls and emeralds; and each person admitted to the delights of the celestial kingdom is provided with a tent of pearls, jacinths and emeralds; is crowned with pearls of incomparable luster, and is attended by beautiful maidens resembling hidden pearls.[8]
