'Years' in the Bible

A day of darkness and gloominess, a day of clouds and thick darkness. As the dawn spreading on the mountains, a great and strong people; there has never been the like, neither will there be any more after them, even to the years of many generations.

I will restore to you the years that the swarming locust has eaten, the great locust, the grasshopper, and the caterpillar, my great army, which I sent among you.
