Psalm 78/Notes/Grammar.V. 10.856105
From Psalms: Layer by Layer
Although probably fronted for poetic symmetry, the appearance of וּ֝בְתוֹרָת֗וֹ before its clause head (לָלֶֽכֶת) is one of the reasons Fassberg provides for considering Ps 78 Archaic/Early Biblical Hebrew, along with Pss 18 and 29 (2019, §8: צורת נסמך לפני מלת יחס "dependent form [placed] before its conjunction"). See also the focus-fronted הֲגַם־לֶ֭חֶם in הֲגַם־לֶ֭חֶם י֣וּכַל תֵּ֑ת (v. 20).
