Biblical texts make clear that marriages between cousins were strongly preferred. Marriages with non-Israelites are treated differently by different texts. Although some passages either limit or prohibit marriages between Israelites and non-Israelites, other biblical texts, such as the book of Ruth, are tolerant of intermarriage. Lev 18 prohibits incest but does not include uncle-niece marriages, which are prohibited in some later Jewish communities, including those responsible for writing the Dead Sea Scrolls . Deut 25:5-10 encourages a custom called levirate marriage, where a widow marries her husband’s brother if her husband has died without children; a similar, though not identical, practice is found in the book of Ruth.
“Married in white, you will have chosen all right.
Married in grey, you will go far away.
Married in black, you will wish yourself back.
Married in red, you’ll wish yourself dead.
Married in blue, you will always be true.
Married in pearl, you’ll live in a whirl.
Married in green, ashamed to be seen,
Married in yellow, ashamed of the fellow.
Married in brown, you’ll live out of town.
Married in pink, your spirits will sink."
