Re: נטילת ידיים היא מצוות טיהור הידיים באמצעות שטיפה, על פי המקובל בהלכה היהודית. That's not an example sentence. That appears to be a definition. "נטילת ידיים is a commandment of purifying the hands by washing, according to the received Jewish oral law." Not sure who added a Hebrew definition on en.wiktionary (all of the above: Isaacmayer9 (talk) 03:11, 3 September 2018 (UTC))
- I added it. And it's not uncommon for first-lines from Wikipedia articles to be used as "example sentences" for foreign languages. It might not be a good example of how the word or phrase is used in a sentence, but it's still useful for learners. — [ זכריה קהת ] Zack. — 20:03, 3 September 2018 (UTC)
