'God is All knowing,' supported by Psalm 147:5 ('his understanding is beyond measure'), Psalm 139:4 ('even before a word is on my tongue... you know it completely'), 1 John 3:19-20 ('God is greater than our hearts, and he knows everything'), Job 37:16 ('the one whose knowledge is perfect'), Proverbs 15:3 ('the eyes of the Lord are in every place'), and Hebrews 4:13 ('no creature is hidden... all are naked and laid bare to the eyes of the one to whom we must render an account').

The hyperbole reading does not survive contact with the genre range of these texts. Hymnic poetry (Ps 147:5, 139:4) does use heightened language, but the doctrine of omniscience is not resting on poetry alone: Job 37:16 occurs inside Elihu's speech building toward the Lord's own theophanic address in Job 38-41, where Yahweh's argument against Job depends precisely on the *literal* contrast between infinite divine knowledge and Job's finite ignorance ('Where were you when I laid the foundations of the earth? Tell me, if you have understanding,' Job 38:4). The Hebrew of 37:16, *tamim de'ah* ('perfect/complete in knowledge'), is doing argumentative work in a legal-theological dispute about theodicy, not merely praising God's greatness. Proverbs 15:3 sits inside a Wisdom collection whose entire genre presupposes that Yahweh's comprehensive moral surveillance is a *reliable premise* for practical ethics ('the eyes of the Lord are in every place, keeping watch on the evil and the good') — the verse would be useless as wisdom instruction if it were merely poetic exaggeration. Hebrews 4:13 and 1 John 3:19-20 are didactic/epistolary, not poetic at all: Hebrews grounds a doctrine of eschatological accountability ('to whom we must render an account') on the literal claim that nothing is hidden from God — the Greek *gymna kai tetrachēlismena* ('naked and laid bare') is sacrificial-cultic imagery for total exposure, used to make a rigorous point about final judgment. 1 John 3:20's *panta ginōskei* ('he knows all things') functions inside a pastoral syllogism reassuring anxious consciences — the argument only works if 'all things' is unrestricted. So across four different genres (wisdom dialogue, wisdom collection, epistolary theology, pastoral epistle) the claim of comprehensive divine knowledge is asserted as literal premise, not merely felt as devotional mood. On Psalm 139 specifically: the psalm is a sustained, structured argument (inescapability spatially, vv.7-12; temporally, vv.1-6, 16; and cognitively, v.4) — 'even before a word is on my tongue' is a *prevenient* knowledge claim (God knows the utterance before it is spoken), which is a stronger and more precise claim than generic praise-hyperbole would require. As for the coherence question: the 'testing to know' texts (Gen 22:12; Deut 8:1-2; Deut 13:3) are addressed in full at omniscient-002 below. The short answer, following Calvin's doctrine of accommodation (*Institutes* 1.13.1) and Aquinas's account of divine knowledge (*Summa Theologiae* I, q.14), is that Scripture routinely narrates God's actions and their effects on human beings from the human, temporal vantage point within the story, without that narrative device asserting a literal epistemic gap in God himself. Aquinas argues (ST I, q.14, a.4) that God's knowledge is not really distinct from God's essence — God does not *have* knowledge the way a creature has a faculty that could be more or less full; God's knowledge simply *is* his one, simple, eternal act of understanding, which as such admits no addition, sequence, or discovery (q.14, a.7 on God's knowledge of things other than himself; q.14, a.13 on future contingents, including free creaturely choices, known in a single eternal act).

Divine omniscience is not an optional add-on to theism; it is a load-bearing premise for the coherence of prophecy, providence, and covenant. If God's knowledge could in principle be mistaken or incomplete, then (a) predictive prophecy (e.g. Isa 46:9-10, 'declaring the end from the beginning'; Dan 2) would be reduced to educated guesswork with no guaranteed fulfillment, (b) providential trust ('all things work together for good,' Rom 8:28) would rest on a God who might simply not see some threat coming, and (c) the entire biblical genre of covenant promise — God binding himself to future outcomes he swears he can guarantee — would be epistemically unwarranted. Omniscience is what makes God's promises more than hopeful predictions. Philosophically, this coheres with Anselmian perfect-being theology: God is 'that than which nothing greater can be conceived.' A being who lacks any item of knowledge is, by definition, surpassable by a being who knows that item in addition to everything else the first being knows — so a maximally great being cannot coherently lack knowledge of anything knowable. This is not merely an argument that the biblical God is probably very knowledgeable; it is a conceptual argument that 'God' (in the sense monotheism, and specifically classical theism, uses the term) picks out a being for whom limited knowledge is a contradiction in terms.
