Theological Words
Eight words that carry the Bible's theology — agape, chesed, logos, hilastērion, berith, shalom, emunah, doxa — each a door into its full workbench page.
Words with the weight of glory in them.
Framework
Why these eight
Some words in Scripture do more work than whole chapters elsewhere. Chesed — the covenant loyal-love of "his mercy endureth for ever" (Ps 136). Berith — covenant itself, the architecture of the whole Bible. Shalom — wholeness, not mere absence of war. Emunah — the firmness behind "the just shall live by his faith" (Hab 2:4). And on the Greek side: agape, the love of 1 Corinthians 13 and "God is love" (1 John 4:8); logos, the Word who "was made flesh" (John 1:14); doxa, the glory the Septuagint re-minted from a word that once meant only "opinion"; hilastērion, the mercy seat itself, applied to Christ at Romans 3:25.
This page is a hub, not a lexicon: each word gets its anchor texts, its Hebrew-to-Greek bridge where the Septuagint built one, and one door into its full workbench page — occurrences, morphology, and the tools, all rendered live from the data floor.

The Septuagint bridges
Between the Testaments stands a translation, and its lexical choices became the New Testament's vocabulary. The LXX chose diathēkē — a unilateral disposition, a will — over synthēkē, a bilateral pact, to render berith; Hebrews 9:15–17 builds its "testament" argument on exactly that choice, and Jeremiah's diathēkē kainē ("new covenant", Jer 31:31 LXX) is the phrase Hebrews 8:8 inherits. It loaded eirēnē, classical Greek for the mere absence of war, with shalom's wholeness — the freight behind Romans 5:1 and John 14:27. It re-minted doxa from "opinion" into the bearer of kavod, the weight of glory — so Isaiah's throne vision (Isa 6:3) can become John's "he saw his glory" (John 12:41). It habitually gave chesed as eleos, mercy — the word that rings through Mary's and Zacharias's songs (Luke 1:50, 54, 72). And it named the ark's lid, the kappōreth, hilastērion — a word that then appears exactly twice in the New Testament: Hebrews 9:5, the literal mercy seat, and Romans 3:25, Christ himself.

Where the founder plants his flag
Word studies are the site's front door to depth — and the classic place to overclaim. The founder's own notes on these words will be planted here. The method caution below (Barr and Carson on the root fallacy and totality transfer, the John 21 agapaō/phileō trap) stays in force regardless: the workbench gives the data; context sets the meaning.

Three platforms where the words stand togetherThe texts
It is of the LORD's mercies that we are not consumed… they are new every morning: great is thy faithfulness.Chesed and emunah in one breath — loyal-love and faithfulness, the covenant-character pair.
And the Word was made flesh, and dwelt among us, (and we beheld his glory…) full of grace and truth.Logos and doxa in a single verse — the Word made flesh, and the glory beheld.
He that loveth not knoweth not God; for God is love.Agape predicated of God himself — the word 1 Corinthians 13 walks through member by member.
Method caution
◈How not to do word studiescontested · three named traps, attributed
The root fallacy
A word’s etymology is not its meaning. The hub above gives histories and bridges because they are illuminating data — never because a root can settle what a verse says.
James Barr· The Semantics of Biblical Language (1961) — cite-only
Illegitimate totality transfer
Importing a word’s entire semantic range into one occurrence. The atlas brief applies this caution by name to shalom: the New Testament context, not the Hebrew range, sets each occurrence’s meaning.

The John 21 trap
The agapaō/phileōalternation of John 21:15–17 is flagged in the site’s same-word research brief as an observation “many overclaim” — this hub names the trap rather than trading on it. The workbench gives the data; context sets the meaning.
“The just shall live by his faith”One line, quoted three times
“The just shall live by his faith” (Hab 2:4 — emunah)
For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith. (Romans 1:17)
But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. (Galatians 3:11)
Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him. (Hebrews 10:38)
