Day 125 What is unabated vigor?

The Book of Deuteronomy says..."Moses was 120 years old when he died. His eye was undimmed, and his vigor unabated." What an amazing observation about Moses! What is unabated vigor? According to the Compact Oxford English Dictionary..."without any reduction in intensity or strength." What a tribute to Moses. He never lost a step by the many years of walking with the Lord!
