Genesis 18:4
wash your feet.In those ancient times, shoes such as ours, were not in use; and the foot was protected only with sandals or soles, fastened round the foot with straps. It was, therefore, not only necessary from motives of cleanliness, but also a very great refreshment, in so hot a country, to get the feet washed at the end of a day's journey; and this is the first thing that Abraham proposes. 19:2; 24:32; 43:24; 1Sa 25:41; Lu 7:44; Joh 13:5-15; 1Ti 5:10tree.Rest in the shade was the second requisite for the refreshment of a weary traveller.
