For I do know

1. Alma 29: 11
     11 Yea, and I also remember the captivity of my fathers; for I surely do know that the Lord 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.
2. Alma 36: 3
     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 trust in God shall be supported in their trials, and their troubles, and their afflictions, and shall be lifted up at the last day.
