'Defiled' in the Bible

“You shall not sow your vineyard with two kinds of seed, or all the produce of the seed which you have sown and the increase of the vineyard will become defiled.

then her former husband who sent her away is not allowed to take her again to be his wife, since she has been defiled; for that is an abomination before the Lord, and you shall not bring sin on the land which the Lord your God gives you as an inheritance.
