"Blessed of the Lord is his land,
With the precious things of heaven, with the dew,
And the deep lying beneath,
With the precious fruits of the sun,
With the precious produce of the months,
With the best things of the ancient mountains,
With the precious things of the everlasting hills,
With the precious things of the earth and its fullness,
And the favor of Him who dwelt in the bush.
Let the blessing come 'on the head of Joseph,
And on the crown of the head of him who was separate from his brothers.'"
