Reference for Pesachim 3:9
מיתיבי (איוב כד, יד) לאור יקום רוצח יקטל עני ואביון ובלילה יהי כגנב
which proves that 'or' is evening? - This is its meaning: praise him all ye stars which give light.

What is its practical bearing? In respect of one who vows [not to benefit] from light. For it was taught: If one vows [not to benefit] from light, he is prohibited the light of stars. An objection is raised: The murderer riseth with the light [or], he killeth the poor and needy, and in the night he is as a thief.<span class="x" onmousemove="('comment',' Job.
