Parashas Eikev · Passuk 7:26
You must not bring an abhorrent thing into your house, or you will be proscribed like it; you must reject it as abominable and abhorrent, for it is proscribed.
Torah Temimah points to Makkot 22b.
TT lemma: ולא תביא תועבה (unit 2 of 7).
English: One who cooks with wood of an asherah is liable to lashes because of “You shall not bring an abomination into your house” (and also because of “nothing of the banned property shall cling to your hand” in Re’eh).
Custom (halakhic application — asherah wood)
Using asherah wood for cooking incurs lashes under this prohibition.
