And there is a difference between the verbכֵהָה (the plague be dim)⁷¹ and the noun כֵהֶה (darkness): The noun teaches that it is dimmed absolutely, while the verb teaches that it is swayed towards the action and it means to say that it is dimmed slightly.

And moreover, when it is written זאת תורת היולדת (This is the law for her that bears)⁷² (as an active participle), it is implied that she is still involved in childbirth; this is the difference between the subject and the adjective יולדה, which teaches that she was found in this state long ago. And they learn from this that she gives birth to many newborns.

And moreover, there is a difference between רבוע (square) – that it is an adjective which indicates that it is square and מרובע (square) – that it teaches about the position that is made in the act of mating. And this is what the sages of blessed memory mean when they say: מי כתיב מרובע? רבוע כתיב (Is it written מרובע? It is written רבוע)⁷³.
