Kommentar zu Bereschit 24:55

ויאמר אחיה ואמה AND HER BROTHER AND HER MOTHER SAID —But where was Bethuel? He wished to prevent the marriage therefore an angel came and killed him (Genesis Rabbah 60:12).

A year. Give her time to adjust to the idea of moving to another country.

ויאמר אחיה ואמה , when there are both major and minor characters in a story, the Torah attributes what is happening primarily to the major character. Although Rivkah’s mother was senior to Lavan, he, in his capacity as the manager of this household was mentioned first. We find something similar in Numbers 12,1 where Miriam, who was junior to Aaron is mentioned first since she did the talking and Aaron only listened. This is also why Esther is mentioned first in Esther 9,29, although the position as prime minister occupied by Mordechai was senior to that of the queen. The initiative of what is reported in the verse was Esther’s, hence her name is mentioned first.
