Family disbanding after the death of the parent

Genesis 50:15-17

  15 ¶ And when Joseph’s brethren saw that their father was dead, they said, ^aJoseph will peradventure hate us, and will certainly requite us all the evil which we did unto him.

  16 And they sent a messenger unto Joseph, saying, Thy father did command before he died, saying,

 

  17 So shall ye say unto Joseph, ^aForgive, I pray thee now, the trespass of thy brethren, and their sin; for they did unto thee evil: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Joseph ^bwept when they spake unto him. 

 

 

Joseph's brothers fear that Joseph will turn against him after their father dies.  Joseph reassures them.

 

The division between the sons of Jacob comes much later, during the days of Rehoboam and Jeroboam (1 Kings 12/2 Chronicles 10)

 

Following the death of their father Lehi, Nephi's brothers seek to kill him, and the family splits in two. (2 Nephi 5:2-7)

2 But behold, their ^aanger did increase against me, insomuch that they did seek to take away my life.

 3 Yea, they did murmur against me, saying: Our younger brother thinks to ^arule over us; and we have had much trial because of him; wherefore, now let us slay him, that we may not be afflicted more because of his words. For behold, we will not have him to be our ruler; for it belongs unto us, who are the elder brethren, to ^brule over this people.

  4 Now I do not write upon these plates all the words which they murmured against me. But it sufficeth me to say, that they did seek to take away my life.

  5 And it came to pass that the Lord did ^awarn me, that I, ^bNephi, should depart from them and flee into the wilderness, and all those who would go with me.

  6 Wherefore, it came to pass that I, Nephi, did take my family, and also ^aZoram and his family, and Sam, mine elder brother and his family, and Jacob and Joseph, my younger brethren, and also my sisters, and all those who would go with me. And all those who would go with me were those who believed in the ^bwarnings and the revelations of God; wherefore, they did hearken unto my words.

  7 And we did take our tents and whatsoever things were possible for us, and did journey in the wilderness for the space of many days. And after we had journeyed for the space of many days we did pitch our tents.
