Exodus 5:7-9

Young's Literal Translation

⁷ `Ye do not add to give straw to the people for the making of the bricks, as heretofore -- they go and have gathered straw for themselves;

⁸ and the proper quantity of the bricks which they are making heretofore ye do put on them, ye do not diminish from it, for they are remiss, therefore they are crying, saying, Let us go, let us sacrifice to our God;

⁹ let the service be heavy on the men, and let them work at it, and not be dazzled by lying words.'
