Exodus 23:19<quoted text> Read... Rev 7: 4-8
These cannot be the tribes of natural Isreal because there never was a tribe of Joseph, the tribes of Ephraim and Dan are not included in the list here, and the levites were set aside for service in connection with the temple but were not reckoned as one of the 12 tribes. See numbers 1: 4-16.)
19 Bring the best of the firstfruits of your soil to the house of the Lord your God.
Aren't we suppose to trust God for the rest of the harvest???
Remember "firstfruits......" refers to the first of something that will be followed by many others.
