"Expedient that ye should"

1. Mosiah 13: 27
     27 And now ye have said that salvation cometh by the law of Moses. I say unto you that it is expedient that ye should ^akeep the law of Moses as yet; but I say unto you, that the time shall come when it shall ^bno more be expedient to keep the law of Moses.
2. Mosiah 23: 7
     7 But he said unto them: Behold, it is not expedient that we should have a king; for thus saith the Lord: Ye shall ^anot esteem one flesh above another, or one man shall not think himself above another; therefore I say unto you it is not expedient that ye should have a king.
3. Mosiah 29: 13, 16
     13 Therefore, ^aif it were possible that you could have ^bjust men to be your kings, who would establish the ^claws of God, and judge this people according to his commandments, yea, if ye could have men for your kings who would do even as my father ^dBenjamin did for this people—I say unto you, if this could always be the case then it would be expedient that ye should always have kings to rule over you.

     16 Now I say unto you, that because all men are not just it is not expedient that ye should have a ^aking or kings to rule over you.
