"Middle aged"

1. Alma 5: 49
   49 And now I say unto you that this is the order after which I am called, yea, to preach unto my beloved brethren, yea, and every one that dwelleth in the land; yea, to preach unto all, both old and young, both bond and free; yea, I say unto you the aged, and also the middle aged, and the rising generation; yea, to cry unto them that they must repent and be born again.
2. D&C 103: 22
   22 Therefore let my servant Joseph Smith, Jun., say unto the strength of my house, my young men and the middle aged—Gather yourselves together unto the land of Zion, upon the land which I have bought with money that has been consecrated unto me.
