Numbers 11:5 - Ellicott's Commentary On The Whole Bible

We remember the fish... — Classical writers and modern travellers agree in bearing testimony to the abundance of the fish in the Nile and in the neighbouring canals and reservoirs. The cucumbers in Egypt are of great size and finely flavoured. The watermelons serve to moderate the internal heat which the climate produces. (See The Land and the Book, p. 508.) The word rendered leeks (in Psalms 104:14, grass for cattle) is supposed by some to denote a species of clover which is peculiar to Egypt, and of which the young and fresh shoots are said to be used as food and to be an excellent stomachic. The onions of Egypt are said to be the sweetest in the world, and they constitute the common food of the lowest class of the people. Garlic is still much used by the modern Arabs. It is only the fish, which was probably equally within the reach of all, of which the Israelites are said to have eaten freely, i.e., not abundantly, but gratuitously. It is probable, however, that many of them cultivated the land to a greater or lesser degree, and so procured vegetables for themselves.
