1 Heb “relying, I relied.” The infinitive absolute precedes the finite verbal form to emphasize the verbal idea. The emphasis is reflected in the translation through the adverb “completely.” Another option is to translate, “I waited patiently” (cf. , , ).
2 Heb “cistern of roaring.” The Hebrew noun בּוֹר (bor, “cistern, pit”) is used metaphorically here of Sheol, the place of death, which is sometimes depicted as a raging sea (see Ps 18:4, 15–16). The noun שָׁאוֹן (sha’on, “roaring”) refers elsewhere to the crashing sound of the sea’s waves (see Ps 65:7).
3 Heb “from the mud of mud.” The Hebrew phrase translated “slimy mud” employs an appositional genitive. Two synonyms are joined in a construct relationship to emphasize the single idea. For a detailed discussion of the grammatical point with numerous examples, see Y. Avishur, “Pairs of Synonymous Words in the Construct State (and in Appositional Hendiadys) in Biblical Hebrew,” Semitics 2 (1971): 17–81.
4 Heb “he established my footsteps.”
