Exodus 5:7

7. 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. The Israelites were employed in this drudgery; and though they still dwelt in Goshen and held property in flocks and herds, they were compelled in rotation to serve in the brick quarries, pressed in alternating groups, just as the fellaheen, or peasants, are marched by press gangs in the same country still. let them go and gather straw for themselves--The enraged despot did not issue orders to do an impracticable thing. The Egyptian reapers in the corn harvest were accustomed merely to cut off the ears and leave the stalk standing.

Verse 7 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.
