וְשׁ֥וֹר וָשֶׂ֖ה שָׂר֣וּעַ וְקָל֑וּט נְדָבָה֙ תַּעֲשֶׂ֣ה אֹת֔וֹ וּלְנֵ֖דֶר לֹ֥א יֵרָצֶֽה׃
Either a bullock or a lamb that hath any thing too long or too short, that mayest thou offer for a freewill-offering; but for a vow it shall not be accepted.
Targum Jonathan on Leviticus
A bullock or a ram that hath superfluity or deficiency of the testicles, you may make a free will offering, but for a vow it will not be acceptable.
