Contradiction with Exodus 13:13
Exodus 13:13 requires the redemption of the firstborn of a donkey by a lamb or alternatively by breaking its neck, whereas Exodus 34:20 requires redemption by offering a lamb without the provision of breaking the neck.
Exodus 13:13: And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem. [lamb: or, kid]
Contradiction with Deuteronomy 15:19
Deuteronomy 15:19 commands not to work the firstlings of herd and flock, which is related but distinct in practice from the redemption terms described in Exodus 34:20.
Deuteronomy 15:19: All the firstling males that come of thy herd and of thy flock thou shalt sanctify unto the LORD thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.
Paradox #1
There may be a perceived inconsistency when comparing the requirement for the redemption of the firstborn with other passages that describe different practices or laws about firstborns. This could create confusion about what specific practices are expected and why they vary.
Paradox #2
Exodus 34:20 mentions redeeming the firstborn of donkeys with a lamb, or breaking its neck if not redeemed. This might seem inconsistent because it involves a practice that doesn't appear directly related to spiritual or moral teachings that are consistent throughout other parts of the Bible, like valuing all life. It focuses on a specific ancient cultural practice that might not align with broader spiritual messages.
Paradox #3
Exodus 34:20 might be seen as inconsistent due to conflicting instructions found elsewhere in the Bible regarding the redemption of the firstborn. In some parts, the Bible refers to redeeming the firstborn with a substitute or ransom, while other sections describe different rituals and laws concerning the firstborn, which could create confusion or inconsistency for readers trying to understand a unified practice.
Paradox #4
Exodus 34:20 talks about redeeming the firstborn of a donkey with a lamb or breaking its neck if not redeemed, and redeeming all firstborn sons. The contradiction could be seen in the value placed on animal life versus human life and the ritualistic practice involved, which might conflict with contemporary views on animal rights and human equality.
