Toar (H8389) describes outward appearance or physical form — used of Joseph's handsome form (Gen 39:6), Rachel's beauty (Gen 29:17), the appearance of the Israelite spies (Num 11:7, the manna description), and the physical description of the suffering servant in Isaiah. The word focuses on the visible, external shape of a person or thing.
The theology of toar reaches its climax in the Suffering Servant passage: 'He had no form [toar] or majesty that we should look at him, and no beauty that we should desire him' (Isa 53:2). The Messiah would be judged by outward appearance and rejected — the opposite of the culturally celebrated Joseph or the tall Saul (1 Sam 9:2). Yet God had warned Samuel: 'Do not look on his appearance (toar)... for the LORD sees not as man sees' (1 Sam 16:7). Toar — visible form — is not where value lies. Christ came in the form of a servant, without impressive toar, so that His glory might be recognized by faith rather than sight.
