I do know

1. Alma 5: 45-46
     45 And this is not all. Do ye not suppose that I ^aknow of these things myself? Behold, I testify unto you that I do know that these things whereof I have spoken are true. And how do ye suppose that I know of their surety?
     46 Behold, I say unto you they are made ^aknown unto me by the Holy Spirit of God. Behold, I have ^bfasted and prayed many days that I might know these things of myself. And now I do know of myself that they are true; for the Lord God hath made them manifest unto me by his Holy Spirit; and this is the spirit of ^crevelation which is in me.
2. Alma 7: 8
     8 Behold, I do not say that he will come among us at the ^atime of his dwelling in his mortal tabernacle; for behold, the Spirit hath not said unto me that this should be the case. Now as to this thing I do not know; but this much I do know, that the Lord God hath power to do all things which are according to his word.
3. Alma 29: 11
     11 Yea, and I also remember the captivity of my fathers; for I surely do know that the ^aLord did deliver them out of bondage, and by this did establish his church; yea, the Lord God, the God of Abraham, the God of Isaac, and the God of Jacob, did deliver them out of bondage.
4. Alma 34: 8
     8 And now, behold, I will ^atestify unto you of myself that these things are true. Behold, I say unto you, that I do know that Christ shall come among the children of men, to take upon him the ^btransgressions of his people, and that he shall ^catone for the sins of the world; for the Lord God hath spoken it.
5. Alma 36: 3, 26, 30
     3 And now, O my son Helaman, behold, thou art in thy youth, and therefore, I beseech of thee that thou wilt hear my words and learn of me; for I do know that whosoever shall put their ^atrust in God shall be supported in their ^btrials, and their troubles, and their afflictions, and shall be ^clifted up at the last day.

     26 For because of the ^aword which he has imparted unto me, behold, many have been born of God, and have ^btasted as I have tasted, and have seen eye to eye as I have seen; therefore they do know of these things of which I have spoken, as I do know; and the knowledge which I have is of God.

     30 But behold, my son, this is not all; for ye ought to know as I do know, that ^ainasmuch as ye shall keep the commandments of God ye shall ^bprosper in the land; and ye ought to know also, that inasmuch as ye will not keep the commandments of God ye shall be cut off from his presence. Now this is according to his word.
6. Alma 40: 9
     9 Therefore, there is a time appointed unto men that they shall rise from the dead; and there is a space between the time of death and the resurrection. And now, concerning this space of time, what becometh of the souls of men is the thing which I have inquired diligently of the Lord to know; and this is the thing of which I do know.
