5:13 “You are the salt 1 of the earth. But if salt loses its flavor, 2 how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people.
1 sn Salt was used as seasoning or fertilizer (BDAG 41 s.v. ἅλας a), or as a preservative. If salt ceased to be useful, it was thrown away. With this illustration Jesus warned about a disciple who ceased to follow him.
2 sn The difficulty of this saying is understanding how salt could lose its flavor since its chemical properties cannot change. It is thus often assumed that Jesus was referring to chemically impure salt, perhaps a natural salt which, when exposed to the elements, had all the genuine salt leached out, leaving only the sediment or impurities behind. Others have suggested that the background of the saying is the use of salt blocks by Arab bakers to line the floor of their ovens; under the intense heat these blocks would eventually crystallize and undergo a change in chemical composition, finally being thrown out as unserviceable. A saying in the Talmud (b. Bekhorot 8b) attributed to R. Joshua ben Chananja (ca.
3 tn Grk “grass of the field.”
4 tn Grk “into the oven.” The expanded translation “into the fire to heat the oven” has been used to avoid misunderstanding; most items put into modern ovens are put there to be baked, not burned.
sn The oven was most likely a rounded clay oven used for baking bread, which was heated by burning wood and dried grass.
5 sn The phrase even more is a typical form of rabbinic argumentation, from the lesser to the greater. If God cares for the little things, surely he will care for the more important things.
6 tn The participle ὄντες (ontes) has been translated concessively.
7 sn The provision of the good gifts is probably a reference to the wisdom and guidance supplied in response to repeated requests. The teaching as a whole stresses not that we get everything we want, but that God gives the good that we need.
8 tn Grk “Truly (ἀμήν, amhn), I say to you.”
9 tn Grk “if two of you…agree about whatever they ask, it will be done for them by my Father who is in heaven.” The passive construction has been translated as an active one in keeping with contemporary English style, and the pronouns, which change from second person plural to third person plural in the Greek text, have been consistently translated as second person plural.
10 tn Grk “and raise up seed,” an idiom for fathering children (L&N 23.59).
11 sn A quotation from Deut 25:5. This practice is called levirate marriage (see also Ruth 4:1-12; Mishnah, m. Yevamot; Josephus, Ant. 4.8.23 [4.254-256]). The levirate law is described in Deut 25:5-10. The brother of a man who died without a son had an obligation to marry his brother’s widow. This served several purposes: It provided for the widow in a society where a widow with no children to care for her would be reduced to begging, and it preserved the name of the deceased, who would be regarded as the legal father of the first son produced from that marriage.
