What are some examples of loyalty, with quotes, in Night?

In chapter 1, the Wiesel family's former maid, Maria, visits the family and begs them to come stay with her at a shelter she has prepared. Elie's father refuses but tells Elie and his sisters they can go if they want to. "Naturally, we refused to be separated."
In chapter 3, at the first selection, Elie is waved to the left; however, he waits to see which way his father is waved, planning to join his father whichever way he goes.
In chapter 4, Franek wants Elie's crown. Elie refuses, so Elie's father is beaten because he cannot march correctly. Elie tries to teach his father to march, but Elie's father cannot get it right. Finally, Elie gives up his crown to save his father.
In chapter 4, the young pipel is tortured and murdered because he, and the oberkapo he served, refused to give up the other names of the people who were involved in the theft of the weapons.
In chapter 5, Elie and his father know they will either stay in the camp together or evacuate the camp together. There is no question of being separated.
In chapter 6, Elie and his father stay together while running. They also make sure to wake each other up so they won't starve to death. An example of disloyalty is when Rabbi Eliahu's son abandons him during the run.
In chapter 7, Elie frantically wakes up his father when the other prisoners think he is dead and are going to throw him off the train. Also, in chapter 7, Elie's father calls Meir Katz over to save him. Another example of loyalty in chapter 7 is when the father catches two pieces of bread: one for himself and one for his son. An example of disloyalty is when the son kills his father for his two pieces of bread.
In chapter 8, Elie remains physically loyal to his father, finding him after the air raid and giving his father his rations. However, he also shows disloyalty by his thoughts, when he hopes he won't find his father after the raid. Also, he shows some disloyalty when he thinks that perhaps he should be having his father's rations. In addition, his thoughts after his father dies are that he is "free."
