I am new to "Mi Yodeya?" and this is my first time asking questions.
First, I have always heard that everything that is written in the Torah has a purposeful meaning; nothing in it is a coincidence or a mistake - has veshalom! My question is, then, why is it written "mishkav zakhar" - 'mishkav' (singular) - and "mishkeve isha" - from 'mishkavim' (plural)? Do males have just one "mishkav" and females more than one? Lastly, what is the meaning of 'mishkav/mishkavim'? I know that individually they mean 'lying/s (as on a bed), and bed/bedding.
I want to understand the phraseology of 'mishkav zakhar'. The only place I remember seeing it is in Numbers 31:17-18. I want to understand it so that I may better understand Lev. 18:22 and 20:13. Numbers 31:17-18 says: " ועתה הרגו כל זכר בטף, וכל אשה ידעת איש למשכב זכר הרגו. וכל הטף בנשים אשר לא ידעו משכב זכר החיו לכם."
