Psalm 19:12-13

Hebrew Key Terms

• H7691 שְׁגִיאָה (shegi'ah) - error, mistake (plural: שְׁגִיאוֹת); from שָׁגָה, H7686
• H5641 סָתַר (sathar) - to hide, conceal (Niphal participle נִסְתָּרוֹת, "hidden faults")
• H5352 נָקָה (naqah) - to be clean, acquit, declare innocent
• H2086 זֵד (zed) - presumptuous, arrogant

Context: David concludes his meditation on God's revelation (heavens declare, law restores) with a prayer for cleansing. He distinguishes between "errors" (sins he doesn't recognize), "hidden faults" (concealed from his awareness), and "willful sins" (deliberate rebellion — the presumptuous sin of Num 15:30). He prays for cleansing from the first two and restraint from the third.

OT-to-OT Development

• Leviticus 4:2 - שְׁגִיאוֹת (errors) is cognate with שְׁגָגָה (inadvertent sin), but by by-form roots — שָׁגָה (H7686) and שָׁגַג (H7683) — not one shared root. The two verses hold no lexeme in common, so this is a supporting / thematic link resting on shared situation, not a demonstrable citation
• Numbers 15:30-31 - Presumptuous sin (בְּיָד רָמָה, "high hand") contrasted with ignorant sin
• Jeremiah 17:9 - "The heart is deceitful above all things"

Connections

• TO: Leviticus 4:2 - Cognate (by-form) vocabulary connecting to the Levitical provision
• FROM OT: Proverbs 20:9 - "Who can say, 'I have kept my heart pure; I am cleansed from my sin'?"
• FROM NT: 1 John 1:8 - "If we say we have no sin, we deceive ourselves"

Christological Connection: David's prayer acknowledges what the Levitical system implied: human self-examination cannot identify all sin. The question "Who can discern his own errors?" expects the answer "No one." This prepares for Christ's priesthood, which deals gently with "those who are ignorant and misguided" (Hebrews 5:2). David cannot cleanse what he cannot see; he must trust God's provision for sins beyond his awareness. Christ's atoning work covers not just the catalog of known sins but the vast terrain of unknown transgressions.

Connection Method(s): Longitudinal Theme; Analogy — David's prayer for cleansing from secret faults applies Levitical categories to personal devotion, developing the longitudinal theme that human self-knowledge is insufficient and analogically points to Christ's comprehensive atonement covering unknown sins.
