Until the sun be hot, i.e. till it be clear and broad day; when enemies approaching may be discovered, and the people of the city will be ready for the defence in case of an assault. While they stand by, i.e. the watches appointed to that end, as is manifest from the following words. Every one to be over against his house, i.e. every one in his turn keeping watch with others in that watching-place which is next to his house.
