Question
Where can I find Rabbis discussion on the age of training and service of the Priest. Especially this quote: "Rabbi Yosef B’chor Shor echoes sentiments expressed by Ramban when he notes that '25 is when lighter work begins, including singing. At age 30, heavier carrying kicks in, as strength kicks in (based on Avot 5:21). The rabbis also taught that at 25 he begins his training, while at 30 he begins to serve.'"

Question
We are designing a Mikvah. Can it have a drain at the bottom of the pool? If so where does the water go to? ( Can't go into sewer system.) If not; how do we get the water out to clean the pool. I surely do not want to be the 14th person who bathes in the same water!! Is there an on line guide available?   Thanks, [name withheld]

Question
My parents are divorced. When I recite Birkat Hamazon at one of their homes and I insert the paragraph for eating a one’s parent’s table, do I recite the words for both parents, or only the parent whose table it is?
