The word את that is used to indicate a direct object will usually be missing. And the sages of blessed memory give interpretations for the wordאת in the Scripture several times. And after investigation, I found that in several places where the direct object is known through for instance a definite article ה or a pronoun, and moreover in a place where the direct object is a noun – the word את will usually come. And in a place where the direct object is unknown – it usually will come without the word את, and when the word את does come, there will be a homiletical interpretation.

And moreover, in a place where the direct object is known but is missing the word את, there will be a homiletical interpretation. And it will always say יכבס בגדיו (he shall wash his clothes), except with a house which is afflicted, where it will say יכבס את בגדיו. This is because whenever one washes clothes, the clothes were not necessarily worn, only afflicted, so the pronoun in בגדיו is not precise; thus, it will be missing the word את. But a house that is afflicted only makes the clothes that were worn unclean, so the the pronoun will be precise; thus, it is written את.
