Where Does the Bible First Mention Marriage?
The Bible first mentions marriage in Genesis 2:24, from the original word basar echad (בשר אחד) — 'one flesh'. 'They shall be one flesh' is the first definition of marriage—a man leaving, cleaving, and being united to his wife, instituted by God before sin entered the world.
