Deuteronomy 1:28 - Clarke's commentary and critical notes on the Bible

Whither shall we go up? our brethren have discouraged our heart, saying, The people is greater and taller than we; the cities are great and walled up to heaven; and moreover we have seen the sons of the Anakims there. Cities - walled up to heaven - That is, with very high walls which could not be easily scaled. High walls around houses, etc., in these parts of Arabia are still deemed a sufficient defense against the Arabs, who scarcely ever attempt any thing in the way of plunder but on horseback. The monastery on Mount Sinai is surrounded with very high walls without any gate; in the upper part of the wall there is a sort of window, or opening, from which a basket is suspended by a pulley, by which both persons and goods are received into and sent from the place. It is the same with the convent of St. Anthony, in Egypt; and this sort of wall is deemed a sufficient defense against the Arabs, who, as we have already observed, scarcely ever like to alight from their horses.
