Oui, je te le recommande: sois fort et résolu, sans peur et sans faiblesse! Car l’Éternel, ton Dieu, sera avec toi dans toutes tes voies."
Tze'enah Ure'enah
“I command you” [1:9]. For I have commanded you that you should go to war, but have respect and also study Torah. It is also written concerning others, Torah and respect and do not fear the nations, since God is with you wherever you will turn.
Rashi
I have already commanded you to be stong and courageous. This was said in reference to actual war, as it is said: ‘Have no fear or trepidation.’ Where was he commanded this? He was so commanded in the time of Moshe, as it is said: ‘and command Yehoshua son of Nun etc.’18Devorim 31:23.
Metzudat David
I have commanded you to be strong in war opposite the enemy and to not be afraid.
