“They blessed Rebekah and said to her,
         “May you, our sister,
         Become thousands of ten thousands,
         And may your descendants possess
         The gate of those who hate them.””  -Gen. 24:60

Rebekah’s mother and her brother Laban pronounce these wonderful blessings upon her as she decides to leave her home and marry Isaac.  Astoundingly and unbeknownst to them, this blessing is almost identical to the one God gave to Abraham after he offered Isaac in Gen. 22:16-17 (emphasis mine):

“By Myself I have sworn, declares the LORD, because you have done this thing and have not withheld your son, your only son, indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens and as the sand which is on the seashore; and your seed shall possess the gate of their enemies.”

The similarity of the blessing is merely further confirmation that the marriage between Isaac and Rebekah was divinely arranged.  Further, we see that such blessings are meant to carry down through the generations, and they do so.

The phrase “possess the gate of  their enemies” may seem obvious in its meaning; to be successful in battle, to win decisive victories, etc.  However it may, on the other hand, mean that they hoped Rebekah’s offspring would have such integrity and wisdom that even their enemies would seek their advice (Haamek Davar).  This interpretation seems more in line with seeking peace before resulting to war.  Ultimately we see instances of both in scripture.
