Covereth his feet — This phrase is used only here, and 1 Samuel 24:3. A late judicious interpreter expounds it, of composing himself to take a little sleep, as was very usual to do in the day — time in those hot countries. And when they did so in cool places, such as this summer parlour unquestionably was, they used to cover their feet. And this may seem to be the more probable, both because the summer parlour was proper for this use, and because this was a more likely reason of their long waiting at his door, lest they should disturb his repose. And this sense best agrees with Saul's case in the cave, when being asleep, David could more securely cut off the lap of his garment.
