Darkness and Revelation

Ipse revelat profunda et abscondita, et novit in tenebris constituta, et lux cum eo est.   Cui Deus revelat profunda, et potest dicere: O profundum divitiarum sapientiae et scientiae Dei, iste, habitante in se Spiritu scrutatur etiam profunda Dei, et in profunda animae suae fodit altissmos puteos, et omnem terram egerit, quae profundas aquas operire consuevit: servatque mandatum Dei, dicens: Bibe aquam de tuis vasis, et de puteorum tuorum fonte. Quodque sequitur: Novit in tenebris constituta, et lux cum eo est: tenebrae significant ignorantiam, et lux scientiam atque doctrinam. Itaque Deum ut perversa non capiant, ita recta ambiunt, atque circumdant, Sive interpretandum est, quod tenebrosa mystica quaeque et profunda significet, juxta illud quod legimus in Proverbiis: Intelligit quoque parabolam et tenebrosum sermonem, hoc ipsum significat quod in Psalmis legimus: Tenebrosa aqua in nubibus aeris. Qui enim ad excelsa conscendit, et terrena deserens, instar avium tenuissimum aerem et aetherea quaeque desiderat, iste nubes efficitur, ad quam veritas Dei pervenit, et quae super sanctos pluere consuevit: repletusque multitudine scientiae, habet multas aquas in corde suo tenebrosas et involutas caligine, quam solus Moyses ingreditur et loquitur Deo facie ad faciem, de quo scriptum est: Posuit tenebras latibulum suum. Sanctus Hieronymus, Commentaria in Daniel, Caput II

It is He who reveals deep and hidden things, and He knows what is placed in darkness, and with Him is light. 1 A man to whom God makes profound revelations and who can say, 'O the depth of the riches of the knowledge and wisdom of God', 2 he is one who, having the Spirit in himself, inquires into the deep things of God, and digs the deepest of wells in the depths of his soul, and he carries off all the earth which is accustomed to conceal the deep waters, and he observes the command of God, which says: 'Drink water from your vessels and from the spring of your wells' 3. As for the words which follow: 'He knows what is placed in the darkness, and with Him is the light,' the darkness signifies ignorance, and the light signifies knowledge and learning. Therefore as wrong cannot hide God away, so right encompasses and surrounds Him. Or we should interpret it to mean all obscure mysteries and deep things, according to what we read in Proverbs: 'He understands also the parable and the dark saying,'  and this meaning is the same as that line we find in the Psalms: 'Dark waters in the clouds of the sky.' 4 For one who ascends to the heights and forsakes the things of earth is like a bird desiring the most rarefied atmosphere and things ethereal, and he becomes like a cloud into which the truth of God penetrates and which is accustomed to rain upon the saints. Replete with a plenitude of knowledge, he has in his heart many dark waters enveloped with deep darkness, which only Moses can penetrate and speak with God face to face, concerning which it is written: 'He has made darkness His hiding-place'. 4 Saint Jerome, from the Commentary on Daniel, Chapter 2 1 Dan 2.22 2 Rom. 11.33 3 Prov. 5.15 4 Ps. 17.12
