Theological Trajectories — Cross-Testament Word Studies¶

The trajectory module stitches together the full lexical journey of a word from Hebrew OT to LXX Septuagint to Greek NT, assessing whether the NT adopts the LXX's vocabulary (high continuity) or diverges to new word choices. The theological_reports module provides 14 pre-built trajectory studies.

Pipeline stages:

1. OT Hebrew stats (word_study)
2. OT to LXX alignment (MACULA Hebrew inline Greek)
3. LXX corpus distribution (lxx.parquet)
4. NT usage (TAGNT parquet)
5. Continuity assessment: high | medium | low | none

14 pre-built terms: bara / berith / ruach / shalom / tsedeq / hesed / yeshua / kavod / ahav / emunah / torah / padah / kaphar / qadosh

Sections:

1. Cross-Testament Trajectory (print_trajectory — shalom, berith, ruach)
2. Starting from Greek (agape)
3. Trajectory Reports
4. Theological Reports Module (all 14 terms)

1. Cross-Testament Trajectory¶

Trace a Hebrew word through its full canonical journey: OT usage statistics, how the LXX translated it, how the LXX word is distributed, and how the NT uses (or avoids) that same Greek word.

shalom (H7965) — the Hebrew concept of peace/wholeness, rendered primarily as eirene in the LXX, which then becomes the NT's peace word.

In [ ]:

from bible_grammar import print_trajectory

# Trace shalom (H7965): OT -> LXX eirene -> NT
print_trajectory('H7965')

from bible_grammar import print_trajectory # Trace shalom (H7965): OT -> LXX eirene -> NT print_trajectory('H7965')

In [ ]:

# Trace berith/covenant (H1285) -> LXX diatheke -> NT
print_trajectory('H1285')

# Trace berith/covenant (H1285) -> LXX diatheke -> NT print_trajectory('H1285')

In [ ]:

# Trace ruach/spirit (H7307) -> LXX pneuma -> NT
print_trajectory('H7307')

# Trace ruach/spirit (H7307) -> LXX pneuma -> NT print_trajectory('H7307')

---

2. Starting from Greek¶

The trajectory pipeline can also start from a Greek NT word and work backwards through the LXX to find the Hebrew antecedents. agape (G26) is the NT's primary love word, but what Hebrew concept does it derive from, and how does the LXX bridge them?

In [ ]:

# Start from Greek: trace NT agape (G26) through LXX back to OT context
print_trajectory('G26')

# Start from Greek: trace NT agape (G26) through LXX back to OT context print_trajectory('G26')

3. Trajectory Reports¶

Save full Markdown + chart reports for individual words. Each report includes OT statistics, LXX alignment table, LXX distribution chart, NT usage, and a continuity assessment.

In [ ]:

from bible_grammar import save_trajectory_report

path = save_trajectory_report(
    'H7965', output_dir='../../../output/reports/ot/lexicon'
)
print(f'Saved: {path}')

from bible_grammar import save_trajectory_report path = save_trajectory_report( 'H7965', output_dir='../../../output/reports/ot/lexicon' ) print(f'Saved: {path}')

4. Theological Reports Module — All 14 Terms¶

The theological_reports module provides 14 pre-built cross-testament trajectory studies for key Hebrew theological terms.

Terms covered: bara / berith / ruach / shalom / tsedeq / hesed / yeshua / kavod / ahav / emunah / torah / padah / kaphar / qadosh

5. Term Map — OT → LXX → NT at a Glance¶

The termmap module produces a compact structured table for any set of Hebrew roots, showing OT occurrence counts, the primary LXX translation equivalent (with IBM Model 1 alignment confidence), and the NT count of that LXX term. It's the same pipeline as trajectory but optimized for side-by-side comparison across many terms at once.

Useful for: quickly surveying a semantic field, building a vocabulary lesson, or comparing how different Hebrew terms for the same concept (e.g., multiple words for love or righteousness) travel into the NT.

from bible_grammar.termmap import term_map, print_term_map, THEOLOGICAL_TERMS

# Single term: berith (covenant)
df = term_map('H1285')
df

# The Hebrew 'love' cluster — three different words, very different NT profiles
# ahav (H0157) = general love; hesed (H2617) = covenantal love; raham (H7355) = compassion
love_terms = ['H0157', 'H2617', 'H7355']
df_love = term_map(love_terms)
print_term_map(df_love)

print_term_map(df_right)
