Job 1-3

Job

1.1 & 1.8 & 2.3 

blameless

      תָּם (tām) perfect.

the verb’s fundamental idea of completeness

tāmam moves naturally toward that which is ethically sound, upright (Ps 19:13 [H 14]). The “perfect” (tāmîm) decision, as made by lots, is the correct one (I Sam 14:41). As made by men, it is the right one (Jud 9:16, 19). Asaph praised the completeness (tōm) or integrity of King David’s heart (Ps 78:72). tāmam is used with the commandments of God meaning to fulfill them (Josh 4:10). The AV translates Job 22:3, “if you make your ways perfect.”
