16 Or perhaps “confident”; Heb “my heart is steadfast.” The “heart” is viewed here as the seat of the psalmist’s volition and/or emotions.
17 Heb “glory,” but that makes little sense in the context. Some view כָּבוֹד (kavod, “glory”) here as a metonymy for man’s inner being (see 459 II כָּבוֹד 5), but it is preferable to emend the form to כְּבֵדִי (kévediy, “my liver”). Like the heart, the liver is viewed as the seat of one’s emotions. See also Pss 16:9; 30:12; 108:1, as well as H. W. Wolff, Anthropology of the Old Testament, 64, and M. Dahood, Psalms (), 1:. For an Ugaritic example of the heart/liver as the source of joy, see G. R. Driver, Canaanite Myths and Legends, 47–48: “her [Anat’s] liver swelled with laughter, her heart was filled with joy, the liver of Anat with triumph.”
18 1007 שַׁחַר takes “dawn” as an adverbial accusative, though others understand it as a personified direct object. “Dawn” is used metaphorically for the time of deliverance and vindication the psalmist anticipates. When salvation “dawns,” the psalmist will “wake up” in praise.
19 Or “the peoples.”
20 Heb “for great upon the sky [or “heavens”] [is] your loyal love.”
21 Or “be exalted.”
22 Heb “over all the earth [be] your splendor.” Though no verb appears, the tone of the statement is a prayer or wish. (Note the imperative form in the preceding line.)
