Exodus 5:7

Ye shall no more give the people straw to make brick,.... Whether this was given and used to mix with the clay, as is done in some places (h), that the bricks made thereof might be firmer and stronger, or to burn them with in the furnaces, or to cover them from the heat of the sun, that they might not dry too soon and crack, is not easy to determine; though it is said that the unburnt bricks of Egypt formerly were, and still are made of clay mixed with straw.

His suggestions were very unreasonable. (1.) That the people were idle, and that therefore they talked of going to sacrifice. The cities they built for Pharaoh, and the other fruit of their labours, were witnesses for them that they were not idle; yet he thus basely misrepresents them, that he might have a pretence to increase their burdens.

Ye shall no more give the people straw to make brick--The making of bricks appears to have been a government monopoly as the ancient bricks are nearly all stamped with the name of a king, and they were formed, as they are still in Lower Egypt, of clay mixed with chopped straw and dried or hardened in the sun.

Straw to make brick - There have been many conjectures concerning the use of straw in making bricks. Some suppose it was used merely for burning them, but this is unfounded. The eastern bricks are often made of clay and straw kneaded together, and then not burned, but thoroughly dried in the sun. This is expressly mentioned by Philo in his life of Moses, who says, describing the oppression of the Israelites in Egypt, that some were obliged to work in clay for the formation of bricks, and others to gather straw for the same purpose, because straw is the bond by which the brick is held together, πλινθου γαρ αχορα δεσμος - Phil. Oper., edit. Mang., vol. ii., p. 86. And Philo’s account is confirmed by the most intelligent travelers. Dr. Shaw says that the straw in the bricks still preserves its original color, which is a proof that the bricks were never burned. Some of these are still to be seen in the cabinets of the curious; and there are several from ancient Babylon now before me, where the straw which was amalgamated with the clay is still perfectly visible. From this we may see the reason of the complaint made to Pharaoh, Exo 5:16: the Egyptians refused to give the necessary portion of straw for kneading the bricks, and yet they required that the full tale or number of bricks should be produced each day as they did when all the necessary materials were brought to hand; so the people were obliged to go over all the cornfields, and pluck up the stubble, which they were obliged to substitute for straw. See Exo 5:12.
