Isaiah 40:6-8 Amplified Bible, Classic Edition (AMPC)

⁶ A voice says, Cry [prophesy]! And I said, What shall I cry? [The voice answered, Proclaim:] All flesh is as frail as grass, and all that makes it attractive [its kindness, its goodwill, its mercy from God, its glory and comeliness, however good] is transitory, like the flower of the field.

⁷ The grass withers, the flower fades, when the breath of the Lord blows upon it; surely [all] the people are like grass.

⁸ The ^[a]grass withers, the flower fades, but the word of our God will stand forever.
