David Grabbe, cuing in on Genesis 1:1 and the Hebrew word translated "in the beginning," informs us that this is also the word for "firstfruits." God takes greater delight in a first fruit than those coming in a later harvest. Wisdom is a first-fruit, and has, itself, first-fruits, including the fear of Lord. The first-fruits were set aside for the priests who served the temple. The firstborn of a man's family is designated as first-fruits, receiving double honor. The physical nation of Israel was God's first fruits, planted to bear fruit, but sadly, like the cursed fig tree, it failed to produce much more than weeds. As Christ's called-out ones, we are the current crop of First Fruits, given a new spiritual birth. God has ordained that we bear spiritual fruit, in a totally different dimension from the first fruits of physical Israel.
The church of God has long acknowledged the biblical analogy of a harvest representing the gathering and eventual resurrection of the saints. Bill Keesee speculates that we can perhaps expand our understanding of the harvest analogy to include other aspects of our preparation for God's Kingdom.
Richard Ritenbaugh, pondering why some authors chose the enigmatic titles of their books, observes that the name of Boaz (a type of Christ) appears many times more than Ruth (a type of the church), indicating Christ's intensive work on behalf of the church, harvesting the firstfruits to the Lord. The whole period from the wavesheaf offering to the offering of the baked loaves constitutes God's harvesting of the firstfruits. It is our obligation to get in line to do our part, as Ruth diligently did her part. Ruth originally was a foreigner (a Moabitess) a type of worldly person outside the covenant, who nevertheless commits herself to Naomi (a type of Israel) and her God, and ultimately becomes redeemed by Boaz, a gracious provider, who instructs the reapers to leave Ruth a generous portion of grain as well as offering her protection and safety, admonishing her not to glean in another field, but to stay close to his women servants, keeping her eyes on the field, following the examples of the other servants, drinking only from what the young men have drawn. In addition to providing graciously, Boaz was a righteous judge, having gathered all the details of Ruth's virtuous and selfless life as he had gathered the grain, winnowing the chaff from the good kernels. After Boaz judged Ruth, he lovingly and lawfully redeemed her as Christ has redeemed His Church.
John Ritenbaugh insists that if we use clear, unambiguous scriptures to clarify ambiguous scriptures, and if we don't try to establish a doctrine on the interpretation of one word, we can avoid the doctrinal blindness caused by presumptive, vain, carnal reasoning. Difficulties some have had about the time of Passover, the Wave sheaf offering, and the time of Pentecost resulted from reversing the process, making assumptions unwarranted by clear scriptural evidence. If we follow the clear instructions about offerings (given to Joshua) in Deuteronomy 12, it becomes abundantly clear that Joshua absolutely would not have made a wave-sheaf offering in Joshua 5. There is also no scriptural basis for assuming that the Wave sheaf offering must occur within the Days of Unleavened Bread.We dare not add to or subtract from God's clear instructions.
