“Thou shalt not eat any abominable thing.”

Not to partake of consecrated animals that were disqualified [for use as sacrifices because] a blemish was intentionally inflicted upon them, as [Deuteronomy 14:3] states: "Do not eat of any abomination." According to the oral tradition, we have learned that the verse refers to consecrated animals that were disqualified for use because of a blemish inflicted upon them.
שלא לאכול פסולי המוקדשין שהוטל בהם מום בכוונה, שנאמר "לא תאכל, כל תועבה" (דברים יד,ג); מפי השמועה למדנו שבפסולי המוקדשין שהוטל בהם מום הכתוב מדבר.
