In Lehi's earlier revelations the Lord communicated with him directly in two open visions, but now as Lehi lay asleep, the Lord conversed with him in a dream.
This verse begins by telling us two things. First, we learn that it was the Lord who told Lehi to warn the people of Jerusalem and tell them what he had seen in his two visions. Secondly, he was told not to go back up to Jerusalem because the people were planning to kill him. Now the Lord told Lehi something which must have come to him as a tremendous surprise.
