Exodus 28:18

And the second row shall be an emerald, a sapphire, and a diamond. The first of these stones is by both the Targums of Onkelos and Jonathan rendered an "emerald", as by us; and which is described by Pliny as of a green colour, exceeding delightful and pleasant, and to which he gives the third place among precious stones; though by many the stone here called Nophec is thought to be the carbuncle, and is so rendered by the Septuagint; the carbuncle of the ancients is no other than what we call the, "ruby"; and which Braunius thinks is here meant, and so Abarbinel, which is just making an exchange of the last stone of the first row for this; and De Dieu observes, that if any chooses to render the preceding stone an emerald, as Braunius does, he must render this a carbuncle or ruby; and if he renders that a carbuncle, then he must this for an emerald.
