What does Genesis 24:56 mean?

Why was Abraham's servant eager to leave with Rebekah so quickly after her family agreed to the marriage proposal? They had requested, very reasonably, 10 days or so delay before sending her off to be married in a strange land.

Abraham's servant insisted on not being delayed. His reason is hard to understand: "since the Lord has prospered my way." Did the servant feel that delaying their departure would somehow dishonor the success God had granted to him? Perhaps he was concerned that, given time to think about their agreement, Rebekah's family might change their mind. He might have assumed that, since God had granted his request to find the right woman so quickly, that God also intended this mission to be completed as soon as possible.

One more possibility is that the servant was concerned Abraham might die before he could get back with this wife for Isaac. Abraham's words to the servant at the beginning of this chapter did sound like those of a dying man. Though Abraham went on to live several more decades, perhaps his health status was questionable for a season. And, lest we forget, Abraham is more than 130 years old at this point (Genesis 17:17; 21:5; 23:1–2).

In any case, the servant wants to leave—immediately!
