nag-iingat ng kagandahang-loob hanggang sa libu-libong salinlahi, nagpapatawad ng kasamaan, ng paghihimagsik, at ng kasalanan; ngunit hindi Niya lubusang pinawawalang-sala ang may sala; pinaparusahan ang kasamaan ng mga ama sa mga anak, at sa mga anak ng mga anak, hanggang sa ikatlo at hanggang sa ikaapat na salinlahi.”
Rashi
נצר חסד means God keeps (stores up) the mercy which a person does in His presence,
Chizkuni
נושא עון ופשע, “He welcomes the penitent, even those who sinned deliberately or out of obstinacy.”
Da'at Zekenim
נוצר חסד לאלפים, “extending kindness to a thousand generations;” G–d undertakes to extend kindness to the descendants of the good and righteous fathers even of sinners. This concept has been repeated in Deuteronomy 7,9: where a time limit of one thousand generations is the limit. Rash’bam explains the apparent contradiction with our verse where the word לאלפים appears to mean at least two thousand, that we find, grammatically speaking, that a fourth generation, normally described as דור רביעי, is on occasion described as רבעים, with the plural mode ending. The same is true here. (Compare our verse) Therefore אלף or אלפים, can mean the same thing on occasion.
