The author of Psalm 19 consciously reflects on the cosmology in Genesis 1 and associated traditions. This reflection involves how the psalmist conceives of the sun, including the celestial feature’s personal nature, responsibility in the cosmic order in terms of calendrical regulation, and its deliberate obedience in the fulfillment of its cultic task. The sun’s obedience serves as a model for sacerdotal devotion, and, just as importantly, allows for the human priest to fulfill his own obligations vis-à-vis properly-timed observance of cultic activities. Of primary importance in all of this, whether at the celestial level or the human level, is the centrality of septenary Sabbath observance, which the sun is charged to mark and the righteous Yahweh devotee is charged to observe. Its importance is implicitly signaled by the psalmist, as it is in Genesis 1: by seven-fold repetition (of Yahweh’s name), and by cryptic allusion (the אות in שׁגיאות).

See, for example, Phillipe Guillaume, “Genesis 1 as Charter of a Revolutionary Calendar”, Theological Review14 (2003), pp. 141-148, and “Tracing the Origin of the Sabbatical Calendar in the Priestly Narrative [Genesis 1 to Joshua 5],” JHS 5  n.p., http://www.jhsonline.org/Articles/article_43.pdf [accessed 30 May 2012]). I remain unconvinced of Guillaume’s suggestion that the Sabbath Calendar ultimately has an origin in Zoroastrian religion. See also Cooley, Poetic Astronomy, pp. 313-20 (especially pp. 314 and 319).

Fishbane, Biblical Text and Texture, p. 87. See also Seybold, Die Psalmen, p. 87; Ross, Commentary, p. 469. Böhler, on the other hand, does note the sevenfold repetition of the divine name, and he also offers some speculation as to its significance: a full septenary count indicates the full presence of Yahweh (“ ‘Der bestirne Himmel über mir”, p. 91).
Thus, HALOT pp. 1412-1413,following THAT 2, p. 871. In contrast, as Milgrom defines it, “the performer of שׁגה [the corresponding verbal root of שׁגגה] is conscious of his act (drinking wine, making love or crossing hills) but not of its consequences” (“The Cultic שׁגגה”, p. 118). Coote, on the other hand, reads שׁגיאות, not as a label on a particular variety of sin, but as a reference to the planets who, unlike the stars, do not follow a straight path (“Psalm 19: Heavenly Law and Order”, pp. 92-93, note 53). While I obviously disagree with his understanding of the term, he is right that the psalmist is, in fact, concerned with celestial activities because it effects his own well-being.
