'Decaying' in the Bible

“But I will remove the northern army far away from you,And I will drive it into a parched and desolate land,With its forward guard into the eastern sea (Dead Sea)And with its rear guard into the western sea (Mediterranean Sea).And its stench will arise and its foul odor of decay will come up [this is the fate of the northern army in the final day of the Lord],For He has done great things.”

Even so, every healthy tree bears good fruit, but the unhealthy tree bears bad fruit.

Jesus said, “Take away the stone.” Martha, the sister of the dead man, said to Him, “Lord, by this time there will be an offensive odor, for he has been dead four days! [It is hopeless!]”

Now I say this, believers, that flesh and blood cannot inherit nor be part of the kingdom of God; nor does the perishable (mortal) inherit the imperishable (immortal).

Therefore we do not become discouraged [spiritless, disappointed, or afraid]. Though our outer self is [progressively] wasting away, yet our inner self is being [progressively] renewed day by day.
