And this shall be a sign unto you, You shall eat this year such things as grow of themselves, and in the second year that which springs of the same; and in the third year sow you, and reap, and plant vineyards, and eat the fruit thereof.

And Hezekiah had said unto Isaiah, What shall be the sign that the LORD will heal me, and that I shall go up into the house of the LORD the third day?

And Isaiah said, This sign shall you have of the LORD, that the LORD will do the thing that he has spoken: shall the shadow go forward ten degrees, or go back ten degrees?
