Yahweh covenants to preserve the plates. Yahweh had shown Nephi that his words would be preserved and would play a major role in the redemption of Israel. Enos apparently did not know this prophecy—hence his urgency to assure the records’ preservation. Therefore, he requires it of Yahweh. The difference in Enos’s case is the covenant. Where Nephi was shown the future, with Enos Yahweh makes his intention to preserve official.
