[73:9] 1 tn Heb “they set in heaven their mouth, and their tongue walks through the earth.” The meaning of the text is uncertain. Perhaps the idea is that they lay claim to heaven (i.e., speak as if they were ruling in heaven) and move through the earth declaring their superiority and exerting their influence. Some take the preposition -בְּ (bet) the first line as adversative and translate, “they set their mouth against heaven,” that is, they defy God.
[78:2] 2 tn Heb “I will open with a wise saying my mouth, I will utter insightful sayings from long ago.” Elsewhere the Hebrew word pair חִידָה+מָשָׁל (mashal + khidah) refers to a taunt song (Hab 2:6), a parable (Ezek 17:2), proverbial sayings (Prov 1:6), and an insightful song that reflects on the mortality of humankind and the ultimate inability of riches to prevent death (Ps 49:4).
