'Forty Years' in the Bible

For Jehovah your God has blessed you in all the works of your hand. He knows your walking through this great wilderness. Jehovah your God has been with you these forty years. You have lacked nothing.

And you shall remember all the way which Jehovah your God led you these forty years in the wilderness in order to humble you, to prove you, to know what is in your heart, whether you would keep His commandments or not.

Your clothing did not wear out on you, nor did your foot swell, these forty years.

And I have led you forty years in the wilderness. Your clothes have not become old on you, and your shoe has not become old on your foot.
