Although often overshadowed by her sister Rachel, what is the significance of Leah's role as the first wife of Jacob in the unfolding of God's covenant with Abraham?

A Leah's lack of beauty symbolized the unworthiness of the Israelites to receive God's favor. B Leah's prolific childbearing, particularly the birth of Judah, ensured the continuation of the Davidic line and ultimately the lineage of Jesus (Matthew 1:2-16). C Leah's constant complaints about Jacob represented the constant complaining of the Israelites in the desert. D Leah's early death showed how little God valued the role of women in the Old Testament.
