Exodus 34:6

'Love is patient' (makrothymei) and 'kind' renders the LXX self-description of the LORD as 'slow to anger (makrothymos) and abounding in steadfast love.' Paul transposes the covenant attributes of God's character onto agape, so that the hymn portrays love with the very predicates of the divine name. High volume, strong coherence: the Exodus formula is the foundational OT portrait of patient, faithful love.

The declaration 'God is love' distills the self-revelation of the LORD as abounding in steadfast love (hesed). John's identification of love with God's very being is the climactic theological development of the Sinai name-formula proclaiming the LORD merciful, gracious, and abounding in lovingkindness.

Paul's repeated 'I obtained mercy' draws on the LORD's self-revelation as merciful and gracious, slow to anger, the foundational OT confession of divine compassion. The mercy shown to the chief of sinners enacts this character of God. Exodus 34:6 is the wellspring of biblical mercy language.

"Compassion, kindness, lowliness, humility, and perseverance" reproduces the cluster of the divine attributes proclaimed at Sinai (compassionate, gracious, slow to anger, abounding in steadfast love). High recurrence: this is the OT's signature self-revelation of God's character, and believers are to put it on in imitation. Coherence with the forgiving-as-the-Lord-forgave clause is exact.

'God, being rich in mercy, for his great love' draws directly on the Sinai self-revelation of YHWH as 'merciful and gracious... abounding in steadfast love.' The pairing of abundant mercy with great love reproduces the chesed-rab formula, a high-volume, recurrent OT confession Paul evokes to ground salvation in God's covenant character.

'How the Lord is full of compassion and mercy' reproduces the LORD's self-revelation, 'merciful and gracious, slow to anger, abounding in steadfast love' — the formula echoed across the Psalter (103:8; 111:4).

'Full of grace and truth' renders the LXX/Hebrew formula 'abounding in steadfast love (hesed) and faithfulness ('emet)' from God's self-revelation to Moses. This is the densest verbal-conceptual borrowing of the Prologue's climax (vv.14,17). Very high thematic coherence: the glory Israel saw at Sinai is now seen in the Word.

The defining self-revelation 'the LORD, a God merciful and gracious' supplies the content of the Father's mercy that disciples are to imitate, and 'kind toward the unthankful and evil' echoes God's compassion on the undeserving. Strong Coherence with the imitatio Dei.

2:4 'riches of his goodness, forbearance, and patience' draws on the covenant self-revelation 'a God merciful and gracious, slow to anger (makrothymos), abounding in steadfast love' — the divine attribute of forbearance Paul says should lead to repentance, not presumption.

The summary confession 'God is love' (repeated) again distills the LORD's self-naming as abounding in steadfast love. John makes the Sinai attribute the definitive predicate of the divine being in which the believer abides.

The LORD proclaims himself 'abounding in steadfast love and faithfulness (emet/aletheia),' the covenant 'truth' that John's prologue already applied to the incarnate Word (1:14, 'full of grace and truth'). Jesus' claim to be 'the truth' thus draws on the Sinai self-revelation of God's faithfulness; medium confidence given the strong Johannine recurrence of 'truth' language.

The self-revelation of the LORD as merciful, gracious, and abounding in steadfast love stands behind the appearance of the kindness and love of God who saves according to his mercy. The grace-formula of Sinai is the theological ground for salvation not by works.

'The love of God' draws on the covenant self-revelation of the LORD as abounding in steadfast love (hesed), the wellspring of Israel's confidence in divine favor. The echo is conceptual, supplying the OT substrate for 'love of God,' with no verbal citation. Contested because 'love of God' is a generic Pauline phrase not demonstrably keyed to this text.

The mercy/compassion pairing of v.15 resonates with the divine-name proclamation that follows in Exodus 34:6, 'merciful and gracious,' the immediate sequel to 33:19 — the same theophanic context Paul mines.
