 (ii) The Redemption of the First-born. According to the law ( Exodus 13:2) every firstborn male. both of human beings and of cattle, was sacred to God. That law may have been a recognition of the gracious power of God in giving human life, or it may even have been a relic of the day when children were sacrificed Lo the gods. Clearly if it had been carried out literally life would have been disrupted. There was therefore a ceremony called the Redemption of the Firstborn ( Numbers 18:16). It is laid down that for the sum of five shekels--approximately 75 pence--parents could, as it were, buy back their son from God. The sum had to be paid to the priests. It could not be paid sooner than thirty-one days after the birth of the child and it might not be long delayed after that.
