און איר װעט ניט טראָגן װעגן דעם אַ זינד, װען איר שײדט אָפּ פֿון דעם דאָס בעסטע דערפֿון. און איר זאָלט ניט פֿאַרשװעכן די הײליקײטן פֿון די קינדער פֿון ישׂראל, כּדי איר זאָלט ניט שטאַרבן.
Rashi
ולא תשאו עליו חטא וגו׳ AND YE SHALL BEAR NO SIN BY REASON OF IT etc. — This implies: consequently if you do not set it aside you will bear sin on that account.
Siftei Chakhamim
Hence if [you do not]. Meaning: This verse does not come to exempt those who separate it. Because why would one assume that they were liable? Rather it comes to make one liable, and from the negative one infers the positive. Accordingly, one inevitably understands that “and you will not die” means “hence if you profane, you will die” because from the negative one infers the positive. For if not so, why would it say “and you will not die”? Why would one assume that one was liable so that a verse is needed to exempt him? Re’m.

ולא תמותו LEST YE DIE — consequently if you do profane them you will die (Bekhorot 26b; cf. Rashi on Exodus 30:20 and Note thereon).
