1 Kings 2:19 & 20

"When Bathsheba went to King Solomon to speak to him for Adonijah, the king stood up to meet her, bowed down to her and sat down on his throne. He had a throne brought for the king's mother, and she sat down at his right hand. 'I have one small request to make of you,' she said. 'Do not refuse me.' The king replied, ' Make it, my mother; I will not refuse you.'" NIV translation

What a beautiful picture we see here of the proper respect a son should have for his mother. We see this in the fact that he stood up, bowed down to her, & had a throne brought for her.

1 Kings 2:21 & 22

"So she said, 'Let Abishag the Shunammite be given in marriage to your brother Adonijah.' King Solomon answered his mother, 'Why do you request Abishag the Shunammite for Adonijah? You might as well request the kingdom for him - after all, he is my older brother - yes, for him and for Abiathar the priest and Joab son of Zeruiah!'" NIV translation

Solomon became angry at this insult but it is clear that Bathsheba had not known what she was asking. In this request, Solomon sees the fact that Adonijah had not given up his hopes of replacing him as king.
