Numbers 4-7

Most of the 7th chapter of numbers is a repetition of the offerings made by each of the tribes of Israel for the dedication of the altar. Knowing that each leader made an identical offering for each tribe adds no excitement or anticipation to the chapter. But is there an important message hidden in the tedium of this reading? I wonder why each tribe didn't try to "out give" their predecessor? Our selfish nature is bound up in elevating self. I think that God told them exactly what to bring as an offering; nothing more or less would be acceptable. The message to Israel was that all are equal before me. The message to us is the same. All believers are equal before God and we are to give exactly what God requires; our very life.
