Exodus 24

 Where previously the children of Israel experienced fear in hearing the voice of the Lord, Moses selected   Aaron, Nadab, Abihu, and seventy more faithful elders to come to the mountain where -

"...they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.

11 And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink."  (Exodus 24:10–11)

Many Christians quote John where he wrote - 

"No man hath seen God at any time..."  (John 1:18)

But the Prophet Joseph Smith added - 

"...except he hath borne record of the Son; for except it is through him no man can be saved."  (John 1:18, JST)

Obviously, these elders saw Jehovah.
