إِشَعْيَاءَ 41:15

هَأَنَذَا قَدْ جَعَلْتُكَ نَوْرَجًا مُحَدَّدًا جَدِيدًا ذَا أَسْنَانٍ. تَدْرُسُ ٱلْجِبَالَ وَتَسْحَقُهَا، وَتَجْعَلُ ٱلْآكَامَ كَٱلْعُصَافَةِ.

Behold, I will make thee a new sharp threshing instrument having teeth: thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.
