And it came to pass that while he was journeying thither, being weighed down with sorrow, wading through much tribulation and anguish of soul, because of the wickedness of the people who were in the city of Ammonihah, it came to pass while Alma was thus weighed down with sorrow, behold an angel of the Lord appeared unto him, saying: … And behold, I am sent to command thee that thou return to the city of Ammonihah… (Alma 8:14, 16).
And the man said unto him: I am a Nephite, and I know that thou art a holy prophet of God, for thou art the man whom an angel said in a vision: Thou shalt receive. Therefore, go with me into my house and I will impart unto thee of my food; and I know that thou wilt be a blessing unto me and my house (Alma 8:20).
