Le Lévitique 5:19 Halakha : Mishneh Torah, Sheqel Dues

And the name of each thing for which its money was inside the box was written on the box on the outside. And there was a stipulation of the court on all of the remnants, that they would [be used] to offer animal burnt-offerings. It comes out that you have learned that all of the money found in the last six is for animal burnt-offerings – and their skins [would go] to the priests, like the rest of all the skins. And all of the money in the third box is to purchase fowl with them – half of them burnt-offerings and half of them sin-offerings. And in the fourth one, it was all [for] burnt-offerings of fowl.
