Chasidut zu Wajikra 14:32

And in the songs of Shabbat (zemirot), we find, “One who keeps the Shabbat – a boy and a girl (bat) – [will be accepted] like a meal offering on the griddle (machbat).” I was asked what is the connection of a boy and a girl to this; also why did it not mention the incense which is more beloved [than a meal offering]? And even though it worked as a rhyme scheme, there is nevertheless surely an explanation for this. And it appears to me that it is [explained] according to that which is written concerning a poor person [who is being purified from tzaraat] (Leviticus 14:32), “whose means are not sufficient in his purification.” And at first glance, this is a wonder – what can he do that about not being able to bring [the full sacrifice]? Why should he be called, someone who is not able to purify himself? (Editor’s note: The question is based on a homiletical reading of the verse. In fact, the verse is simply describing this person, as someone whose means did not suffice for the full sacrifice, but is nevertheless completely purified with what he brings.)
