Rashi on Exodus 5:11/רש"י על שמות ה׳:י״א

1אתם לכו קחו לכם תבן GO, YE, TAKE TO YOURSELVES STRAW — and you will have to go pretty quickly,

2כי אין נגרע מעבודתכם דבר FOR THERE SHALL NOT BE DIMINISHED OF YOUR WORK A SINGLE THING from the whole total of bricks which you used to make daily when straw was supplied to you, ready to use, from the king’s store.
