Yesaya 1:20

1:20 But if you refuse and rebel,

you will be devoured ¹  by the sword.”

Know for certain that the Lord has spoken. ² 

Yesaya 40:5

40:5 The splendor ³  of the Lord will be revealed,

and all people ⁴  will see it at the same time.

For ⁵  the Lord has decreed it.” ⁶ 

[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).

[40:5]  ³ tn Or “glory.” The Lord’s “glory” is his theophanic radiance and royal splendor (see Isa 6:3; 24:23; 35:2; 60:1; 66:18-19).

[40:5]  ⁴ tn Heb “flesh” (so KJV, ASV, NASB); NAB, NIV “mankind”; TEV “the whole human race.”

[40:5]  ⁵ tn Or “indeed.”

[40:5]  ⁶ tn Heb “the mouth of the Lord has spoken” (so NASB, NIV, NRSV).
