A voice says, “Cry!”
And I said, “What shall I cry?”
All flesh is grass,
and all its constancy is like the flower of the field.
The grass withers, the flower fades when the breath of the Lord blows on it;
surely the people are grass.
The grass withers, the flower fades,
but the word of our God will stand for ever.

Isaiah 40:6-8 (ESVUK)
