95. But, their body being subtile, equally subtile and delicate must be its food. And, just as perfumes and other vaporous and volatile substances, when adverse to their nature, offend and put them to flight, as testified by what we related above (N^{rs} 71 and 72), in the like manner, when agreeable, they delight in and feed upon them. Now, as is written by Cornelius, “_Manna is nothing but an emanation of water and earth, refined and baked by the heat of the sun, and then coagulated and condensed by the cold of the following night_;” of course, I am speaking of the Manna sent down from Heaven for the nourishment of the Hebrews, and which differs all in all from nostrate or medicinal manna; the latter, in fact, according to Ettmuller (_Dilucid. Physiol._, ch. 1), “_is merely the juice or transudation of certain trees which, during the night, gets mixed up with dew, and, the next morning, coagulates and thickens in the heat of the sun_.” The manna of the Hebrews, on the contrary, derived from other principles, far from coagulating, liquefied in the heat of the sun, as is shown by Scripture, _Exodus_, ch. 16, v. 22. The manna of the Hebrews was therefore undoubtedly of a most subtile substance, consisting as it did of emanations of earth and water, and being dissolved by the sun and made to disappear: consequently, it may very well have been the food of the animals we are speaking of, and thus have been truly called by David _Bread of Angels_. 96. Alia auctoritas habetur in Evangelio Joannis, in quo, =Johannes=, c. 10. v. 16., ita dicitur: =Alias oves habeo, quæ non sunt ex hoc ovili, et illas oportet me adducere, et vocem meam audient, et fiet unum ovile, et unus Pastor=. Si quæramus quænam sint oves, quæ non sunt ex hoc ovili, et qualenam sit ovile de quo loquitur Christus Dominus, respondent communiter Expositores unum ovile Christi esse Ecclesiam, ad quam perducendi erant per prædicationem Evangelii Gentiles, qui erant oves alterius ovilis, ab ovili Hebræorum: opinantur enim Synagogam esse Christi ovile, quia dicebat David, =Psal. 94.= v. 9: =Nos populus ejus et oves pascuæ ejus=; et quia Messias promissus fuerat Abraham et David oriturus ex eorum semine, et a populo Hebræo expectatus, et a Prophetis qui Hebræi erant vaticinatus, et ejus adventus, conversatio, passio, mors et resurrectio in sacrificiis, cultu, et ceremoniis Hebræorum legis erant præfigurata.
