¹ tn Heb “the sons of Asaph [were] upon the hand of Asaph, the one prophesying upon the hands of the king.”

¹ tn Heb “and his brother Asaph, the one who stood at his right hand.”

¹ tc The reading ᾿Ασάφ (Asaph), a variant spelling on ᾿Ασά (Asa), is found in the earliest and most widespread witnesses (P^1vid א B C [D^luc] ƒ^{1, 13} 700 it co). Although Asaph was a psalmist and Asa was a king, it is doubtful that the author mistook one for the other since other ancient documents have variant spellings on the king’s name (such as “Asab,” “Asanos,” and “Asaph”). Thus the spelling ᾿Ασάφ that is almost surely found in the initial text of Matt 1:7-8 has been translated as “Asa” in keeping with the more common spelling of the king’s name.

¹ tn Heb “David and the officers of the army set apart for service the sons of Asaph and Heman and Jeduthun, the ones prophesying by harps, by lyres, and by cymbals.”

¹ tc ᾿Αμώς (Amōs) is the reading found in the earliest and best witnesses (א B C [D^luc] Γ Δ Θ ƒ¹ 33 it sa bo), and as such is most likely autographic. This is a variant spelling of the name ᾿Αμών (Amōn). The translation uses this more well-known spelling “Amon” which is found in the Hebrew MT and the majority of LXX mss. See also the textual discussion of “Asa” versus “Asaph” (vv. 7-8); the situation is similar.

¹ tc Heb “The first lot went to Asaph, to Joseph.” Apparently the recurring formula, “and his sons and his relatives, twelve” has been accidentally omitted from the Hebrew text at this point (see vv. 10-31; the formula is slightly different in v. 9b). If the number “twelve” is not supplied here, the total comes to only 276, not the 288 required by v. 7.

¹ tn The disjunctive vav (ו) here introduces a new section, listing the various duties of the clan in the sanctuary. The Gershonites had a long tradition of service here. In the days of David Asaph and his family were prominent as musicians. Others in the clan controlled the Temple treasuries. But in the wilderness they had specific oversight concerning the tent structure, which included the holy place and the holy of holies.

¹ tc A few significant mss (א* Θ ƒ^{1, 13} 33) identify the prophet as Isaiah, a reading that is significantly harder than the generic “prophet” because the source of this prophecy is not Isaiah but Asaph in Ps 78. Jerome mentioned some mss that had “Asaph” here, though none are known to exist today. This problem is difficult because of the temptation for scribes to delete the reference to Isaiah in order to clear up a discrepancy. Indeed, the vast majority of witnesses have only “the prophet” here (א¹ B C D L W Γ Δ 0233 0242 565 579 700 1241 1424 M lat sy co). However, as B. M. Metzger points out, “if no prophet were originally named, more than one scribe might have been prompted to insert the name of the best known prophet—something which has, in fact, happened elsewhere more than once” (TCGNT 27). In light of the paucity of evidence for the reading ᾿Ησαΐου, as well as the proclivity of scribes to add his name, it is probably best to consider the shorter reading as authentic.

³ tn In the Qal this verb, זָכָה (zakhah), means to be (morally) “clean; pure.” Here in the Piel it is factitive to “make clean” (so NRSV) or “keep clean” (so NIV). This verb only appears 8 times in the Bible, but this phrase “to cleanse the heart/mind” also occurs in Ps 73:13, where Asaph despairs of having cleansed his heart (or kept it clean). Ps 119:9 remarks that one can keep your path clean by carefully observing God’s word. And Isa 1:16 advises cleansing oneself by putting away and ceasing to do evil. In an ultimate sense, no one has kept a clean heart in every regard. However these other passages suggest that one can repent in order to cleanse the heart and attend to God’s word to keep it clean. The question thus points out the inherent lack of purity and poses the obligation to take steps to safeguard purity. In other words, since my heart is not (natively) pure, what do I need to do to keep it pure (as in being true to God not in a sense of works adding up to purity)?
