Joshua 1:8

I fear, however, lest by too much negligence and dullness of heart the divine volumes be not only veiled to us but also sealed, so that "if a book should be put into the hands of a man who cannot read, he would say, 'I cannot read'; if it should be put into the hands of a man who can read, he would say, 'It is sealed.' " Whence it is shown that we must not only employ zeal to learn the sacred literature, but we must also pray to the Lord and entreat "day and night" that the lamb "of the tribe of Judah" may come and himself taking "the sealed book" may deign to open it.

You should not be like a wanderer, rambling about the streets, without just cause, to spy out those who live wickedly. But by minding your own trade and employment, endeavor to do what is acceptable to God. And keeping in mind the oracles of Christ, meditate in the same continually. For so the Scripture says to you: "You shall meditate in his law day and night; when you walk in the field, and when you sit in your house, and when you lie down, and when you rise up, that you may have understanding in all things." No, although you are rich and so do not want a trade for your maintenance, don't be one that wonders and walks around at random; but either go to some that are believers, and of the same religion, and confer and discourse with them about the lively oracles of God. Or if you stay at home, read the books of the Law, of the Kings, with the Prophets; sing the hymns of David; and peruse diligently the gospel, which is the completion of the other.

Next, on what subjects and to what extent may we philosophize? On matters within our reach, and to such an extent as the mental power and grasp of our audience may extend. No further, lest, as excessively loud sounds injure the hearing, or excess of food the body, or, if you will, as excessive burdens beyond the strength injure those who bear them, or excessive rains the earth; so these too, being pressed down and overweighted by the stiffness, if I may use the expression, of the arguments should suffer loss even in respect of the strength they originally possessed. Now, I am not saying that it is not needful to remember God at all times; ... I must not be misunderstood, or I shall be having these nimble and quick people down upon me again. For we ought to think of God even more often than we draw our breath; and if the expression is permissible, we ought to do nothing else. Yea, I am one of those who entirely approve that Word which bids us meditate day and night, and tell at eventide and morning and noon day, and praise the Lord at every time; or, to use Moses' words, whether a man lie down, or rise up, or walk by the way, or whatever else he be doing -and by this recollection we are to be moulded to purity. So that it is not the continual remembrance of God that I would hinder, but only the talking about God; nor even that as in itself wrong, but only when unseasonable; nor all teaching, but only want of moderation. As of even honey repletion and satiety, though it be of honey, produce vomiting; and, as Solomon says and I think, there is a time for every thing, and that which is good ceases to be good if it be not done in a good way; just as a flower is quite out of season in winter, and just as a man's dress does not become a woman, nor a woman's a man; and as geometry is out of place in mourning, or tears at a carousal; shall we in this instance alone disregard the proper time, in a matter in which most of all due season should be respected?
