This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.
  لاَ يَبْرَحْ سِفْرُ هَذِهِ الشَّرِيعَةِ مِنْ فَمِكَ, بَلْ تَلْهَجُ فِيهِ نَهَاراً وَلَيْلاً, لِتَتَحَفَّظَ لِلْعَمَلِ حَسَبَ كُلِّ مَا هُوَ مَكْتُوبٌ فِيهِ. لأَنَّكَ حِينَئِذٍ تُصْلِحُ طَرِيقَكَ وَحِينَئِذٍ تُفْلِحُ.
