Helaman 10:11-12

"And now behold, I command you, that ye shall go and declare unto this people, that thus saith the Lord God, who is the Almighty: Except ye shall repent ye shall be smitten, even unto destruction.

And behold, now it came to pass that when the Lord had spoken these words unto Nephi, he did stop and did not go unto his own house, but did return unto the multitudes who were scattered about upon the face of the land, and began to declare unto them the word of the Lord which had been spoken unto him, concerning their destruction if they did not repent."

Previously, Nephi was preaching to the people and many did not believe him. Many wanted to put him in jail. So, Nephi went home and pondered what the Lord had helped him with. As he traveled home he received this commandment from God that he should continue to preach. Nephi immediately turned around and returned to preach repentance unto the people. Nephi was obedient immediately. He did not go home first, rather he followed the command right then and there.
