Read Isaiah 37:27 Using Other Translations
Therefore their inhabitants were of small power, they were dismayed and confounded: they were as the grass of the field, and as the green herb, as the grass on the housetops, and as corn blasted before it be grown up.
while their inhabitants, shorn of strength, are dismayed and confounded, and have become like plants of the field and like tender grass, like grass on the housetops, blighted before it is grown.
That is why their people have so little power and are so frightened and confused. They are as weak as grass, as easily trampled as tender green shoots. They are like grass sprouting on a housetop, scorched before it can grow lush and tall.
