nōṣêr ḥesed, “keeping loyal-love” — the same ḥesed of v.6, now stored and guarded “for the thousands.” Exodus 20:6 echoes this with ʻōśeh (“doing”) rather than nōṣêr (“keeping”).

nōśê ʻāwōn — Maclaren parses the threefold catalogue: ʻāwōn (iniquity, twistedness), pešaʻ (transgression, rebellion/apostasy), ḥaṭṭāʼâh (sin, missing the mark) — three angles on one human ruin, fully covered by one forgiveness.

wənaqqêh yənaqqeh — the crux. The doubled root nâqâh (H5352, to be clean/clear, hold guiltless) is the Hebrew infinitive-absolute intensifier (figura etymologica): the verb is repeated to make it emphatic, hence “he will by no means clear.” It is the very verb behind “the LORD will not hold guiltless” in the third commandment (Exodus 20:7), and the rare pairing recurs in Numbers 14:18 and Nahum 1:3. The plain reading (LXX, AV, Keil, Pulpit) keeps justice intact — note that “the guilty” is supplied, absent in Hebrew (Benson); a long minority (Maimonides, De Dieu, Poole) revocalizes the same intensive to “in destroying he will not utterly destroy,” turning justice into clemency. The FSSB keeps the majority reading and names the dispute.
