¹¹ “Ask the Lord your God for a sign of confirmation, Ahaz. Make it as difficult as you want—as high as heaven or as deep as the place of the dead.^[a]”

³⁰ Then Isaiah said to Hezekiah, “Here is the proof that what I say is true:

⁷ “‘And this is the sign from the Lord to prove that he will do as he promised: ⁸ I will cause the sun’s shadow to move ten steps backward on the sundial^[a] of Ahaz!’” So the shadow on the sundial moved backward ten steps.

²² And Hezekiah had asked, “What sign will prove that I will go to the Temple of the Lord?”

⁸ Meanwhile, Hezekiah had said to Isaiah, “What sign will the Lord give to prove that he will heal me and that I will go to the Temple of the Lord three days from now?”

⁹ Isaiah replied, “This is the sign from the Lord to prove that he will do as he promised. Would you like the shadow on the sundial to go forward ten steps or backward ten steps?^[a]”

¹⁰ “The shadow always moves forward,” Hezekiah replied, “so that would be easy. Make it go ten steps backward instead.” ¹¹ So Isaiah the prophet asked the Lord to do this, and he caused the shadow to move ten steps backward on the sundial^[b] of Ahaz!

²⁹ Then Isaiah said to Hezekiah, “Here is the proof that what I say is true:

³⁶ Then Gideon said to God, “If you are truly going to use me to rescue Israel as you promised, ³⁷ prove it to me in this way. I will put a wool fleece on the threshing floor tonight. If the fleece is wet with dew in the morning but the ground is dry, then I will know that you are going to help me rescue Israel as you promised.” ³⁸ And that is just what happened. When Gideon got up early the next morning, he squeezed the fleece and wrung out a whole bowlful of water.

³⁹ Then Gideon said to God, “Please don’t be angry with me, but let me make one more request. Let me use the fleece for one more test. This time let the fleece remain dry while the ground around it is wet with dew.” ⁴⁰ So that night God did as Gideon asked. The fleece was dry in the morning, but the ground was covered with dew.

The Sign of Jonah

³⁸ One day some teachers of religious law and Pharisees came to Jesus and said, “Teacher, we want you to show us a miraculous sign to prove your authority.”

³⁹ But Jesus replied, “Only an evil, adulterous generation would demand a miraculous sign; but the only sign I will give them is the sign of the prophet Jonah. ⁴⁰ For as Jonah was in the belly of the great fish for three days and three nights, so will the Son of Man be in the heart of the earth for three days and three nights.

¹⁰ “As these men watch you, Jeremiah, smash the jar you brought.

Jeremiah’s Shattered Jar

19 This is what the Lord said to me: “Go and buy a clay jar. Then ask some of the leaders of the people and of the priests to follow you.
