[Avodah] min hatorah

[Rich, Joel]

The Gemara chulin 17b asks "Minayin lbdikat sakin min hatorah"(from where do we know that a shechita knife must be checked) and answers with a pasuk from navi. I couldn't find another gemara that asks this question and answers with a pasuk not from the Torah. Thoughts?
