[7:9] 1 tn The term חֵךְ (khek, “palate, mouth”) is often used as a metonymy for what the mouth produces, e.g., the mouth is the organ of taste (Ps 119:103; Job 12:11; 20:13; 34:3; Prov 24:13; Song 2:3), speech (Job 6:30; 31:30; 33:2; Prov 5:3; 8:7), sound (Hos 8:1), and kisses (Song 5:16; 7:10) (HALOT 313 s.v. חֵךְ; BDB 335 s.v. חֵךְ). The metonymical association of her palate/mouth and her kisses is made explicit by RSV which translated the term as “kisses.”
[7:9] 2 tc The MT reads שִׁפְתֵי יְשֵׁנִים (shifte yÿshenim, “lips of those who sleep”). However, an alternate Hebrew reading of שְׂפָתַי וְשִׁנָּי (sÿfata vÿsinna, “my lips and my teeth”) is suggested by the Greek tradition (LXX, Aquila, Symmachus): χείλεσίν μου καὶ ὀδοῦσιν (ceilesin mou kai odousin, “my lips and teeth”). This alternate reading, with minor variations, is followed by NAB, NIV, NRSV, TEV, NLT.
