Psalm 24/Notes/Textual.vv. 1-2.478278
From Psalms: Layer by Layer
v. 1 – Note that the LXX has a longer superscription, including of the first day of the week (Ψαλμὸς τῷ Δαυιδ· τῆς μιᾶς σαββάτων), possibly hinting at a reference "to the history of the work of creation" (Delitzsch 1883, 410). It is common for LXX psalms to contain reference to the days of the week and Sabbath liturgy, where this is limited to Psalm 92 in the MT. (See the exegetical issue The Sabbath Day in Psalm 92 and references therein.)
