Musar zu Tehillim 85:10

“When you go out to war, etc., and see horses and chariots - forces larger than yours - have no fear of them” (Deuteronomy 20:1). We were warned with this that if a person sees trouble nearby, the salvation of the Lord should be in his heart and he should trust in it - like the matter that is stated (Psalms 85:10), “His salvation is near those who fear Him”; and likewise is it written (Isaiah 51:12), “What ails you that you fear man who must die.”
