67 Heb “lives.” The noun חַיִּים (khayyim, “lives”) functions as an adverbial accusative of manner: “alive.” The form is a plural of state, used to describe a condition of life which encompasses a long period of time—in this case a person’s entire life. Murder cuts short a person’s life.
68 The noun שְׁאוֹל (shé’ol) can mean (1) “death,” cf. ; (2) “the grave,” cf. , , (3) “Sheol” as the realm of departed spirits, cf. “the nether world,” and (4) “extreme danger.” Here it is parallel to the noun בוֹר (vor, “the Pit”) so it is the grave or more likely “Sheol” (cf. , ). Elsewhere Sheol is personified as having an insatiable appetite and swallowing people alive as they descend to their death (e.g., Num 16:30, 33; Isa 5:14; Hab 2:5). In ancient Near Eastern literature, the grave is often personified in similar manner, e.g., in Ugaritic mythological texts Mot (= “death”) is referred to as “the great swallower.”
69 Heb “and whole.” The vav (ו) is asseverative or appositional (“even”); it is omitted in the translation for the sake of style and smoothness. The substantival adjective תָּמִים (tamim, “whole; perfect; blameless”) is an adverbial accusative describing the condition and state of the object. Used in parallel to חַיִּים (khayyim, “alive”), it must mean “full of health” ( 1071 תָּמִים 2). These cutthroats want to murder a person who is full of vigor.
