"You shall no longer supply the people with straw for making bricks. They must go and gather their own straw.

Genesis 11:3
And they said to one another, "Come, let us make bricks and bake them thoroughly." So they used brick instead of stone, and tar instead of mortar.

Exodus 5:6
That same day Pharaoh commanded the taskmasters of the people and their foremen:

Exodus 5:8
But require of them the same quota of bricks as before; do not reduce it. For they are lazy; that is why they are crying out, 'Let us go and sacrifice to our God.'

You shall no more give the people straw to make brick, as heretofore: let them go and gather straw for themselves.
