And this shall be a sign to you: you shall eat this year such things as grow of themselves, and in the second year that which springs up of the same. And in the third year, sow and reap and plant vineyards and eat the fruits of them.

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

And Isaiah said, This will be the sign from Jehovah, that Jehovah will do the thing which He has spoken. Shall the shadow go forward ten steps, or go back ten steps?
