Today’s daf reminds me of an assignment done by our two year olds every year in the preschool (it was done by both of my boys too). Before Rosh HaShana, all the nursery children are to bring in three apples. They do a series of activities with the apples, but the one that reminds me of today’s daf is that each child takes a turn lying on the floor while their classmates measure how tall they are in apples. One will be 25 apples tall, another 27 . . . it’s adorable.
Today’s daf is trying to establish a standard for how big a cubit is. In doing so, they want to still validate other ways to take measurement. So, much of the page talks about what different food items we use to measure things.
Honey, i.e., dates from which date honey is extracted, also determines a measure, as with regard to eating on Yom Kippur, a large date-bulk (if you eat a bite of food in the quantity equivalent to as much as a large date, you’ve broken the fast)
Barley is also used as a basis for measurements, as we learned in a mishna: A bone from a corpse the size of a grain of barley imparts ritual impurity through contact and by being carried, but it does not impart impurity by means of a tent,
Wheat is used to measure how long we can be in a contaminated home before our clothing is rendered impure. One log of wine renders a nazarite as having broken her vow, and forty se’ah of water are necessary for ritual immersion.
Growing up my mom always used the top segment of her thumb to measure things. She said it was roughly an inch – she had her measuring tool always with her.
While none of this is too profound yet. It does have me thinking about how we use different standards to measure different things. And begs the question: Shouldn’t we use different standards when measuring a politician, than a regular joe? Shouldn’t we use different standards when measuring people in the context of other times than today? Should’t we use different standards when measuring aptitude for those who have had every opportunity including private tutors and test prep courses than those who have not?
Standards only work within particular confines. Once out of those confines, we need different points of comparison to take an accurate measure.
