يَشُوع 1:7

إِنَّمَا كُنْ مُتَشَدِّدًا، وَتَشَجَّعْ جِدًّا لِكَيْ تَتَحَفَّظَ لِلْعَمَلِ حَسَبَ كُلِّ ٱلشَّرِيعَةِ ٱلَّتِي أَمَرَكَ بِهَا مُوسَى عَبْدِي. لَا تَمِلْ عَنْهَا يَمِينًا وَلَا شِمَالًا لِكَيْ تُفْلِحَ حَيْثُمَا تَذْهَبُ.

Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper whithersoever thou goest.
