The answer is: Judah

Gen 44:18-33

In the dramatic tale of Genesis, it is Judah who volunteers to take Benjamin's place as a servant in Egypt. This selfless act emerges in a moment of deep familial tension after Joseph, still disguised as a powerful Egyptian ruler, frames Benjamin for theft. The backstory is rich and intense; Jacob's sons had already caused him heartache when they returned with the bloodied cloak of their other son Joseph, whom they believed lost forever.

Judah's willingness to sacrifice himself for Benjamin reveals the profound evolution in his character. Earlier in Genesis, we see Judah as more self-serving; he was the one who wanted to sell Joseph into slavery rather than protect him. This 180-degree transformation signifies maturation and a deeper understanding of familial loyalty and responsibility. Like the reversal of fortunes prominently placed throughout the Scriptures, Judah now bravely advocates for his brother.

This moment serves as a significant echo of later themes within the Bible—one can think of figures like Jesus, who also takes on others' burdens. What makes this even more compelling is that Judah ultimately becomes the ancestor of the line leading to kings like David, foreshadowing the lasting impact of his choice. It’s a beautiful reminder of redemption and the possibilities that come from standing up not just for oneself, but also for our loved ones in their times of need.
