ויפקד, מנה יוסף להיות עמם ולשרתם: ויפקוד, he appointed Joseph to be their constant companion and personal valet. We are told this so that we can understand why Joseph enjoyed their confidence and they told him their dreams.

ימים, ולא זכר כמה, ואפשר כי היה שנה שהיו במשמר וכן ימים תהיה גאולתו (ויקרא כ"ה): ימים, the Torah does not give further details about how many days. It is possible that the word ימים means “a year,” as it appears in that sense in Leviticus 25,29.
