Isaiah 40:7 New English Translation

⁷The grass dries up,
the flowers wither,
when the wind sent by the Lord^[a] blows on them.
Surely humanity^[b] is like grass.

Isaiah 40:7 tn The Hebrew text has רוּחַ יְהוָה (ruakh yehvah), which in this context probably does not refer to the Lord’s personal Spirit. The phrase is better translated “the breath of the Lord,” or “the wind of [i.e., sent by] the Lord.” The Lord’s sovereign control over nature, including the hot desert winds that dry up vegetation, is in view here (cf. Ps 147:18; Isa 59:19).
Isaiah 40:7 tn Heb “the people” (so KJV, ASV, NAB, NASB, NIV, NRSV).
