Moses is making reference to the “book of life,” a figurative book representing God’s memory of those who have passed away and whom he will one day resurrect (Rev. 3:5).
Shortly after Israel solemnly vowed to obey God, Moses was on Mt. Sinai receiving instructions on how to institute pure worship (Exo. 24:3, 12).
Meanwhile, back at the camp, the people were growing restless.
They concluded something must have happened to Moses and asked his brother, Aaron, to make them a god- a tangible one that they could worship then and there (Exo. 32:1).
Aaron succumbed to the pressure and figured the gold idol he made was just as well a representation of Jehovah (Exo. 32:2-5).
Jehovah was furious and he explored the option of exterminating the nation in order to form a new nation stemming from Moses (Exo. 32:10).
Moses humbly appealed to God on behalf of his people, begging him to take other factors into account (Exo. 32:11-13).
Of course, Jehovah already knew he was going to give Israel the opportunity to repent time and again, but by planting the option of extermination, we can appreciate Moses’s self-sacrificing attitude and the great love he felt for those whom he led.
Moses was willing to be wiped out from existence because the extermination of his people would have signified he had failed them as a leader.
This leads me to ask myself: do I show similar concern for the welfare of those who have been commended to my spiritual tutelage?
