[1:20] 1 sn The wordplay in the Hebrew draws attention to the options. The people can obey, in which case they will “eat” v. 19 (תֹּאכֵלוּ [to’khelu], Qal active participle of אָכַל) God’s blessing, or they can disobey, in which case they will be devoured (Heb “eaten,” תְּאֻכְּלוּ, [tÿ’ukkÿlu], Qal passive/Pual of אָכַל) by God’s judgment.
[1:20] 2 tn Heb “for the mouth of the Lord has spoken.” The introductory כִּי (ki) may be asseverative (as reflected in the translation) or causal/explanatory, explaining why the option chosen by the people will become reality (it is guaranteed by the divine word).
