"for every vow": to exclude what has already been vowed. "for every vow": to include (the harlot's hire as interdicted even for) a bamah (a temporary altar).
"into the house of the L-rd your G-d" to exclude (from the interdict) the bullock of the sin-offering, (i.e., the red heifer, which is not brought into the Temple, but is slaughtered outside the encampment [viz. Bamidbar 19:3]). These are the words of R. Eliezer. The sages say: to include (as interdicted) gold-foil (for the Temple).
"for every vow": to include (as interdicted) (even) a bird. For I would think: If sacrificial offerings, which are invalidated by blemishes, are not subject to "hire" and "exchange," then birds, which are not invalidated by blemishes — how much more so should they not be subject to "hire" and "exchange." It is, therefore, written "for every vow," to include birds. I might think that (also interdicted is) the hire (that he gives the harlot) for abstention (from remunerative labor for the time period required for the act); it is, therefore, written "for the abomination of the L-rd" (i.e., the hire forbidden is that for the act itself).
