Lift up your head and be of good cheer, for behold, the time is at hand, and on this night shall the sign be given, and on the morrow come I into the world.

And it came to pass that the words which came unto Nephi were fulfilled, for behold, at the going down of the sun, there was no darkness; and the people began to be astonished, because there was no darkness when the night came.

And it came to pass also, that a new star did appear, according to the word. [And] the more part of the people did believe, and were converted unto the Lord. And Nephi went forth among the people,baptizing unto repentance.
