'Diminish' in the Bible

According to the multitude of years thou shalt increase the price thereof, and according to the fewness of years thou shalt diminish the price of it: for according to the number of the years of the fruits doth he sell unto thee.

I for my part will do this to you: I will inflict horror on you, consumption and fever, which diminish eyesight and drain away the vitality of life. You will sow your seed in vain because your enemies will eat it.

I will send the wild animals against you and they will bereave you of your children, annihilate your cattle, and diminish your population so that your roads will become deserted.
