The answer is: His father sent a servant back to Mesopotamia to choose a wife from his own family

Gen 24:2-4

In the story of Isaac and Rebekah, as outlined in Genesis 24, we find an interesting and thoughtful process for arranging a marriage. It wasn't just a simple match; it involved a quest—an expedition filled with divine guidance and a showcase of the priorities of love and commitment. Abraham was determined that his son, Isaac, marry someone from his lineage, which reflects the cultural context of maintaining family ties and heritage.

The servant’s mission to Mesopotamia had layers of significance. First, it highlights the importance of family connections in the society of the time; marrying outside the clan was avoided to preserve heritage and faith. Additionally, this servant is not named, but it's implied that he is a faithful servant, embodying loyalty—in stark contrast to the reckless romantic notions popular today. His heartfelt prayer to ask for a sign from God is a salient moment, displaying an early form of proactive seeking for divine will, underscoring how religion permeates daily life decisions.

A fun tidbit: when the servant found Rebekah, she offered water not only to him but also to his camels—a practical sign of her character and kindness. Ethically, we might reflect on the traits we value when choosing partners. Also noteworthy is how the story emphasizes duty and devotion over mere infatuation—a reminder that love often blends practicality with deep emotional connections. The love story of Isaac and Rebekah becomes a model not only of arranged marriage but of the intersection between faith and personal choices.
