Reference for Deuteronomy 22:9

לֹא־תִזְרַ֥ע כַּרְמְךָ֖ כִּלְאָ֑יִם פֶּן־תִּקְדַּ֗שׁ הַֽמְלֵאָ֤ה הַזֶּ֙רַע֙ אֲשֶׁ֣ר תִּזְרָ֔ע וּתְבוּאַ֖ת הַכָּֽרֶם׃ (ס)

Thou shalt not sow thy vineyard with two kinds of seed; lest the fulness of the seed which thou hast sown be forfeited together with the increase of the vineyard.
