Allusion3
A deliberate verbal borrowing without a citation formula.
'God is faithful, through whom you were called' (v.9) echoes the covenant formula that 'the LORD your God is the faithful God who keeps covenant.' Volume is good on the distinctive predicate 'faithful' applied to God as the guarantor of a calling, and the covenant-keeping theme coheres with Paul's assurance of preservation to the end.
Medium confidence'Know that YHWH your God is the faithful God who keeps covenant' grounds Paul's 'as God is faithful' and the certainty that all God's promises are confirmed (Yes/Amen). The covenant-keeping faithfulness of God is the theological basis for Paul's argument that his word, mirroring God's, is not equivocating Yes-and-No. Good thematic coherence.
Medium confidence'But the Lord is faithful' draws on the covenantal confession that the Lord is the faithful God who keeps covenant. The predicate 'faithful' (pistos) of God is rooted in this Deuteronomic and broader OT formula of divine covenant fidelity.

A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The pairing of loving God with keeping his commandments matches the covenant formula describing God's faithfulness to 'them that love him and keep his commandments.' John inverts the perspective to the believer's side but preserves the same Deuteronomic word-pair. The covenantal idiom of love-plus-obedience is distinctively Mosaic.
Medium confidenceGod keeps covenant 'with those who love him and keep his commandments,' the precise love+keep-commandments pairing echoed in 14:15 and 14:21. Recurrence of this formula across Deuteronomy raises Volume; the contestation is that John supplies the idiom without a citation marker.
Medium confidence'Know that the LORD your God is the faithful God' underlies 'God is faithful' (v.13). The covenant-faithfulness predicate is a Deuteronomic commonplace Paul likely draws on for assurance amid testing.
Low confidence'Know therefore that the LORD your God... is the faithful God' undergirds Paul's assurance 'He who calls you is faithful' (5:24). A faint covenantal echo of God's reliability to fulfill his word.
