The answer is: Abimelech

Genesis 20:2 - Abimelech, king of Gerar, took Sarah into his harem after Abraham said she was his sister, but God intervened to prevent anything from happening.

The story of Sarah and Abimelech, while filled with drama, reveals a strong theme of divine protection. It's intriguing to note that Abraham, out of fear for his safety, lied about his relationship with Sarah—a narrative common in ancient times with cultures frequently blending family ties and power dynamics through marriage. Abraham wasn’t alone; his son Isaac would find himself in a similar situation with Abimelech’s descendants, suggesting a recurring theme of trust issues with foreign rulers.

Abimelech’s character shines through this story; he was depicted as a faithful and righteous king who, despite the circumstances, is responsive to God's warning in a dream. This account provides an enduring lesson on the importance of integrity, as well as a reminder that divine interference can lead to the preservation of truth and virtue, against the expectations of human deception.

Here's a fun piece of trivia: the word "harem" actually refers simply to a designation for women living in separate quarters and doesn’t have the same salacious connotation as in today's interpretations. In the context of biblical history, such structures were common and held significant implications regarding status and power, affecting inter-political relations.

Moreover, many scholars see this story as an early reflection of the motifs that play into larger narratives of liberation and faith critiquing human fear contrasted with divine provision. Interestingly, devilish duplicity (Abraham's lie) was counteracted by a divine dose of grace—leading to both awareness and a sense of integrity recognized by Abimelech after divine intervention. Isn't it fascinating how ancient narratives continue to echo quietly into our modern lives?
