Exodus 34:6
5 The Lord descended in the cloud and stood with him there and proclaimed the Lord by name. 6 The Lord passed by before him and proclaimed: “The Lord, the Lord, the compassionate and gracious God, slow to anger, and abounding in loyal love and faithfulness, 7 keeping loyal love for thousands, forgiving iniquity and transgression and sin. But he by no means leaves the guilty unpunished, responding to the transgression of fathers by dealing with children and children’s children, to the third and fourth generation.”
Sirach 2:11
Ben Sira, Ecclesiasticus10 Consider the generations of old and see: has anyone trusted in the Lord and been disappointed? Or has anyone persevered in the fear of the Lord and been forsaken? Or has anyone called upon him and been neglected? 11 For the Lord is compassionate and merciful; he forgives sins and saves in time of distress. 12 Woe to timid hearts and to slack hands, and to the sinner who walks a double path!
Notes and References
"... In the reader-oriented approach, any marker can trigger a connection between texts, and readers are free to pursue any type of intertextual relationship they wish. For example, the theme of fire might induce an interpreter to read the story of “strange fire” in Leviticus 10 with passages about immolating children in the Book of Jeremiah, without implying that the latter borrowed from the former or vice versa ... The author-oriented approach, however, works on the principle that the author has purposely embedded markers in the alluding text, and the reader’s goal is to identify those markers and construe the alluding text in light of the evoked one. Authors have three main options at their disposal for creating such markers: explicit citation, direct allusion, and implicit allusion. (In addition, a text may sometimes employ an unmarked citation, as when Sirach 2:11 quotes Exodus 34:6, or when Sirach 24:23 cites Deuteronomy 33:4) ..."
