Quotation2
A formal citation — high verbal volume, often introduced by a saying-formula.
'You shall worship the Lord your God, and you shall serve him only' renders Deuteronomy 6:13 (LXX, which adds 'worship/proskyneo' and 'only/mono'). High Volume verbatim citation; the Shema context (Deut 6) anchors the second/third temptation answers in Israel's covenant loyalty.
High confidenceJesus' climactic reply (v.10) 'You shall worship the LORD your God, and you shall serve him only' quotes Deut 6:13 (LXX adds 'only/alone'). High Volume formula citation; the demand for exclusive worship answers Satan's demand to be worshiped (v.9).
High confidenceEcho3
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
'To serve a living and true God' picks up the Shema-context command to fear YHWH and serve (latreuein) him only, the exclusive-service demand that idolatry violates. The Deuteronomic 'serve him alone' is the positive correlate of turning from idols; coherence is strong, volume moderate.
Medium confidenceThe command to fear God and 'swear by his name' frames the legitimacy of calling God to witness an oath, which Paul does regarding his change of travel plans. The contact is to the sanctioned practice of God-invoking oaths rather than to the verse's wording. Faint echo.
Low confidence'before God, I'm not lying' is an oath/truth-asseveration appealing to God as witness, the practice grounded in swearing 'by his name.' The solemn God-as-witness formula has deep OT roots; low because it is a conventional oath idiom, not a specific citation.
