Deuteronomy 8:3

8:3 So he humbled you by making you hungry and then feeding you with unfamiliar manna. ¹  He did this to teach you ²  that humankind ³  cannot live by bread ⁴  alone, but also by everything that comes from the Lord’s mouth. ⁵ 

Luke 4:4

4:4 Jesus answered him, “It is written, ‘Man ⁶  does not live by bread alone.’” ⁷ 

[8:3]  ¹ tn Heb “manna which you and your ancestors did not know.” By popular etymology the word “manna” comes from the Hebrew phrase מָן הוּא (man hu’), i.e., “What is it?” (Exod 16:15). The question remains unanswered to this very day. Elsewhere the material is said to be “white like coriander seed” with “a taste like honey cakes” (Exod 16:31; cf. Num 11:7). Modern attempts to associate it with various desert plants are unsuccessful for the text says it was a new thing and, furthermore, one that appeared and disappeared miraculously (Exod 16:21-27).

[8:3]  ² tn Heb “in order to make known to you.” In the Hebrew text this statement is subordinated to what precedes, resulting in a very long sentence in English. The translation makes this statement a separate sentence for stylistic reasons.

[8:3]  ³ tn Heb “the man,” but in a generic sense, referring to the whole human race (“mankind” or “humankind”).

[8:3]  ⁴ tn The Hebrew term may refer to “food” in a more general sense (cf. CEV).

[8:3]  ⁵ sn Jesus quoted this text to the devil in the midst of his forty-day fast to make the point that spiritual nourishment is incomparably more important than mere physical bread (Matt 4:4; cf. Luke 4:4).

[4:4]  ⁶ tn Or “a person.” The Greek word ὁ ἄνθρωπος (Jo anqrwpo") is used generically for humanity. The translation “man” is used because the emphasis in Jesus’ response seems to be on his dependence on God as a man.

[4:4]  ⁷ tc Most mss (A [D] Θ Ψ [0102] Ë^1,13 33 Ï latt) complete the citation with ἀλλ᾿ ἐπὶ παντὶ ῥήματι θεοῦ (ajll’ ejpi panti rJhmati qeou, “but by every word from God”), an assimilation to Matt 4:4 (which is a quotation of Deut 8:3). The shorter reading is found in א B L W 1241 pc sa. There is no good reason why scribes would omit the rest of the quotation here. The shorter reading, on both internal and external grounds, should be considered the original wording in Luke.
