义人的祷告必蒙应允 耶稣基督是中保

and Nebuchadnezzar said to them, “Is it true, Shadrach, Meshach and Abednego, that you do not serve my gods or worship the image of gold I have set up?  (Daniel 3:14 NIV)
你们再听见角、笛、琵琶、琴、瑟、笙，和各样乐器的声音，若俯伏敬拜我所造的像，却还可以；若不敬拜，必立时扔在烈火的窑中，有何神能救你们脱离我手呢？” (但以理书 3:15 和合本)
Now when you hear the sound of the horn, flute, zither, lyre, harp, pipe and all kinds of music, if you are ready to fall down and worship the image I made, very good. But if you do not worship it, you will be thrown immediately into a blazing furnace. Then what god will be able to rescue you from my hand?”  (Daniel 3:15 NIV)
沙得拉、米煞、亚伯尼歌对王说：“尼布甲尼撒啊，这件事我们不必回答你，  (但以理书 3:16 和合本)
Shadrach, Meshach and Abednego replied to him, “King Nebuchadnezzar, we do not need to defend ourselves before you in this matter.  (Daniel 3:16 NIV)
即便如此，我们所事奉的　神能将我们从烈火的窑中救出来。王啊，他也必救我们脱离你的手；  (但以理书 3:17 和合本)
If we are thrown into the blazing furnace, the God we serve is able to deliver us from it, and he will deliver us from Your Majesty’s hand.  (Daniel 3:17 NIV)
即或不然，王啊，你当知道我们决不事奉你的神，也不敬拜你所立的金像。” (但以理书 3:18 和合本)
But even if he does not, we want you to know, Your Majesty, that we will not serve your gods or worship the image of gold you have set up.”  (Daniel 3:18 NIV)
那时，尼布甲尼撒王惊奇，急忙起来，对谋士说：“我们捆起来扔在火里的不是三个人吗？”他们回答王说：“王啊，是。”  (但以理书 3:24 和合本)
Then King Nebuchadnezzar leaped to his feet in amazement and asked his advisers, “Weren’t there three men that we tied up and threw into the fire?” They replied, “Certainly, Your Majesty.”  (Daniel 3:24 NIV)
王说：“看哪，我见有四个人，并没有捆绑，在火中游行，也没有受伤；那第四个的相貌好像神子。” (但以理书 3:25 和合本)

Nebuchadnezzar then approached the opening of the blazing furnace and shouted, “Shadrach, Meshach and Abednego, servants of the Most High God, come out! Come here!” So Shadrach, Meshach and Abednego came out of the fire,  (Daniel 3:26 NIV)
那些总督、钦差、巡抚，和王的谋士一同聚集看这三个人，见火无力伤他们的身体，头发也没有烧焦，衣裳也没有变色，并没有火燎的气味。  (但以理书 3:27 和合本)

尼布甲尼撒说：“沙得拉、米煞、亚伯尼歌的　神是应当称颂的！他差遣使者救护倚靠他的仆人，他们不遵王命，舍去己身，在他们　神以外不肯事奉敬拜别神。  (但以理书 3:28 和合本)
Then Nebuchadnezzar said, “Praise be to the God of Shadrach, Meshach and Abednego, who has sent his angel and rescued his servants! They trusted in him and defied the king’s command and were willing to give up their lives rather than serve or worship any god except their own God.  (Daniel 3:28 NIV)
