Psalms 18:33 - Coke's Commentary on the Holy Bible

He maketh my feet like hinds' feet, &c.— i.e. "Hath endowed me with agility and vigour, and made me swift to run, so that I can easily ascend the highest hills." This was reckoned a very honourable qualification among the ancient warriors; who, as they generally fought on foot, were enabled by their agility and swiftness speedily to run from place to place, give orders, attack their enemies, defend their friends, or for any other purposes that the service might require of them; many instances of which we have in the battles of Homer and Virgil. See 2 Samuel 1:23. 1 Chronicles 12:8. This qualification was peculiarly useful to David, as the country of Judaea, and some of those wherein he was obliged to make war, were very mountainous and steep.
