'Years' in the Bible

For the children of Israel had walked forty years in the wilderness, till the whole nation of men of war had perished who had come out of Egypt, who had not hearkened to the voice of Jehovah; to whom Jehovah had sworn that he would not show them the land which Jehovah had sworn unto their fathers that he would give us, a land flowing with milk and honey.

Forty years old was I when Moses the servant of Jehovah sent me from Kadesh-barnea to search out the land; and I brought him word again as it was in my heart.

And now behold, Jehovah has kept me alive, as he said, these forty-five years, since Jehovah spoke this word to Moses, when Israel wandered in the wilderness; and now behold, I am this day eighty-five years old.

And it came to pass after these things, that Joshua the son of Nun, the servant of Jehovah, died, a hundred and ten years old.
