لِمَاذَا تَقُولُ يَا يَعْقُوبُ وَتَتَكَلَّمُ يَا إِسْرَائِيلُ: «قَدِ اخْتَفَتْ طَرِيقِي عَنِ الرَّبِّ وَفَاتَ حَقِّي إِلهِي»؟ أَمَا عَرَفْتَ أَمْ لَمْ تَسْمَعْ؟ إِلهُ الدَّهْرِ الرَّبُّ خَالِقُ أَطْرَافِ الأَرْضِ لاَ يَكِلُّ وَلاَ يَعْيَا. لَيْسَ عَنْ فَهْمِهِ فَحْصٌ. يُعْطِي الْمُعْيِيَ قُدْرَةً، وَلِعَدِيمِ الْقُوَّةِ يُكَثِّرُ شِدَّةً. اَلْغِلْمَانُ يُعْيُونَ وَيَتْعَبُونَ، وَالْفِتْيَانُ يَتَعَثَّرُونَ تَعَثُّرًا. وَأَمَّا مُنْتَظِرُو الرَّبِّ فَيُجَدِّدُونَ قُوَّةً. يَرْفَعُونَ أَجْنِحَةً كَالنُّسُورِ. يَرْكُضُونَ وَلاَ يَتْعَبُونَ. يَمْشُونَ وَلاَ يُعْيُونَ.
(إش٤٠ :٢٧ -٣١ )

Why do you say, O Jacob, and complain, O Israel, "My way is hidden from the LORD; my cause is disregarded by my God"? Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.

(Isaiah 40:27~31, NIV)
