A man is named at the moment he gives, because the sacrifice is what makes him someone. Elizur son of Shedeur is recorded not for what he owned but for what he surrendered, the oxen and rams and lambs handed over to the fire. Identity is forged in the giving-up, and the leader who brings his full portion writes himself into a story larger than his single life.
The gift outlasts its giver. His name survives attached to an act of costly reconciliation, one link in a chain of leaders each doing the same difficult thing in his own turn. To step forward and pay the price openly, under your own name, is how a person earns a place in something that will continue after he is gone.
