To
Beseech
is to,

Ask or pray with urgency;
also called supplicating, or entreating, or imploring.
I beseech you therefore, brethren,
by the mercies of God,
that you present your bodies a living sacrifice,
holy, acceptable unto God,
which is your reasonable service. 
And be not conformed to this world:
but be ye transformed by the renewing of your mind, that ye may prove what is that
good, and acceptable, and
perfect, will of God.

Romans   
12:1-2
