Quick answer

Judah tells Onan to fulfill the brother-in-law's duty and raise up offspring for the dead Er.

Overview

This levirate custom, later codified in the Law (Deuteronomy 25:5-6), preserved a deceased man's name and inheritance through a child borne by his widow. Judah rightly invokes the duty, reflecting concern for family continuity. The custom safeguards the line through which Messiah would come.
