And all verbs for which it is impossible for them to be without a subject – the one language will be in active and passive, מלוה לוה(to lend/to borrow), מכה מוכה (to hit/to be hit), רוצח נרצח (to murder/to be murdered). And if the language is unusual between them – it is depicted that one is without its associate: As with נותן לוקח (give/take) - it is depicted as taking without necessarily giving.

And moreover, קונה מוכר (sell/acquire) is depicted as acquiring without necessarily being sold. And this is the difference between the verb כרה (buy) and the verb קנה (acquire): כרה is only from the seller with a price. And קנה can be through any manner - קונה שמים וארץ (Maker of heaven and earth)⁵⁴. אשת המת קניתי (the wife of the dead)⁵⁵.
