Lately I have been noticing that the scriptures partly define knowing as seeing, here are some examples I have saved.
Mosiah 1:6 O my sons, I would that ye should remember that these sayings are true, and also that these records are true. And behold, also the plates of Nephi, which contain the records and the sayings of our fathers from the time they left Jerusalem until now, and they are true; and we can KNOW of their surety because we have them before our EYES.
Helaman 7:29 Behold now, I do not say that these things shall be, of myself, because it is not of myself that I know these things; but behold, I know that these things are true because the Lord God has made them known unto me, therefore I testify that they shall be.
3 Nephi 12:1 And it came to pass that when Jesus had spoken these words unto Nephi, and to those who had been called, (now the number of them who had been called, and received power and authority to baptize, was twelve) and behold, he stretched forth his hand unto the multitude, and cried unto them, saying: Blessed are ye if ye shall give heed unto the words of these twelve whom I have chosen from among you to minister unto you, and to be your servants; and unto them I have given power that they may baptize you with water; and after that ye are baptized with water, behold, I will baptize you with fire and with the Holy Ghost; therefore blessed are ye if ye shall believe in me and be baptized, after that ye have SEEN me and KNOW that I am.
