Daniel 10:2

They say that dreams are more sure and clear when they happen towards the end of the night, because then the vigour of the soul emerges, and heavy sleep departs. As to the seasons of the year, dreams are calmer in spring, since summer relaxes, and winter somehow hardens, the soul; while autumn, which in other respects is trying to health, is apt to enervate the soul by the lusciousness of its fruits. Then, again, as regards the position of one’s body during sleep, one ought not to lie on his back, nor on his right side, nor so as to wrench his intestines, as if their cavity were reversely stretched: a palpitation of the heart would ensue, or else a pressure on the liver would produce a painful disturbance of the mind. …

This principal species in the category of dietary restriction may already afford a prejudgment concerning the inferior operations of abstinence also, as being themselves too, in proportion to their measure, useful or necessary. For the exception of certain kinds from use of food is a partial fast. Let us therefore look into the question of the novelty or vanity of xerophagies, to see whether in them too we do not find an operation alike of most ancient as of most efficacious religion. I return to Daniel and his brethren, preferring as they did a diet of vegetables and the beverage of water to the royal dishes and decanters, and being found as they were therefore “more handsome” (lest any be apprehensive on the score of his paltry body, to boot!), besides being spiritually cultured into the bargain. …

XX . For even now, on the tenth day of the month Gorpiæus, when they assemble together, they read the Lamentations of Jeremiah, in which it is said, “The Spirit before our face, Christ the Lord was taken in their destructions;” and Baruch, in whom it is written, “This is our God; no other shall be esteemed with Him. He found out every way of knowledge, and showed it to Jacob His son, and Israel His beloved. Afterwards He was seen upon earth, and conversed with men.” And when they read them, they lament and bewail, as themselves suppose, that desolation which happened by Nebuchadnezzar ; but, as the truth shows, they unwillingly make a prelude to that lamentation which will overtake them. …

2. Besides, you have in your Book of Daniel the account of the three youths, which you will find it difficult to reconcile with the opinion that to abstain from meats is the doctrine of devils. For we are told that they abstained not only from what the law forbade, but even from what it allowed; and you are wont to praise them, and count them as martyrs; though they too followed the doctrine of devils, if this is to be taken as the apostle’s opinion. And Daniel himself declares that he fasted for three weeks, not eating flesh or drinking wine, while he prayed for his people. How is it that he boasts of this doctrine of devils, and glories in the falsehood of a lying spirit?

You see from how many points he instructs them in the love that was shown them and the honor that was done them. And what is there that God hath not done for us? The world He hath made corruptible for us, and again for us incorruptible. He suffered His Prophets to be ill-treated for our sake, sent them into captivity for us, let them fall into the furnace, and undergo ills without number. Nay, He made them prophets for us, and the Apostles also He made for us. He gave up for us His Only-Begotten, He punisheth the devil for us, He hath seated us on the Right Hand, He was reproached for us. “For the reproaches of them that reproached thee,” it says, “fell upon me.” ( Ps. lxix. 9 .) Yet still, when we are drawing back after so great favor, He leaveth us not, but again entreats, and on our account inciteth others to entreat for us, that He may show us favor. And so it was with Moses. …

So far, indeed, as I in my ignorance know, to begin with inferior and more dense things, God, knowing the denseness of the Israelites and their carnal love and propensity towards matter in everything, made this law: first, in order that the servant and the cattle should rest as it is written, for the righteous man regardeth the life of his beast : next, in order that when they take their ease from the distraction of material things, they may gather together unto God, spending the whole of the seventh day in psalms and hymns and spiritual songs and the study of the divine Scriptures and resting in God. For when the law did not exist and there was no divinely-inspired Scripture, the Sabbath was not consecrated to God. …
