   Syn: To Beg, Ask, Request.

   Usage: To ask (not in the sense of inquiring) is the generic
          term which embraces all these words. To request is
          only a polite mode of asking. To beg, in its original
          sense, was to ask with earnestness, and implied
          submission, or at least deference. At present,
          however, in polite life, beg has dropped its original
          meaning, and has taken the place of both ask and
          request, on the ground of its expressing more of
          deference and respect. Thus, we beg a person's
          acceptance of a present; we beg him to favor us with
          his company; a tradesman begs to announce the arrival
          of new goods, etc. Crabb remarks that, according to
          present usage, "we can never talk of asking a person's
          acceptance of a thing, or of asking him to do us a
          favor." This can be more truly said of usage in
          England than in America.
          [1913 Webster]

   [Summary?]

   (2000-12-16)


Easton's 1897 Bible Dictionary:

Beg
   That the poor existed among the Hebrews we have abundant
   evidence (Ex. 23:11; Deut. 15:11), but there is no mention of
   beggars properly so called in the Old Testament. The poor were
   provided for by the law of Moses (Lev. 19:10; Deut. 12:12;
   14:29). It is predicted of the seed of the wicked that they
   shall be beggars (Ps. 37:25; 109:10).

     In the New Testament we find not seldom mention made of
   beggars (Mark 10:46; Luke 16:20, 21; Acts 3:2), yet there is no
   mention of such a class as vagrant beggars, so numerous in the
   East. "Beggarly," in Gal. 4:9, means worthless.


The Devil's Dictionary (1881-1906):

BEG, v.  To ask for something with an earnestness proportioned to the
belief that it will not be given.

    Who is that, father?

                          A mendicant, child,
    Haggard, morose, and unaffable -- wild!
    See how he glares through the bars of his cell!
    With Citizen Mendicant all is not well.

    Why did they put him there, father?

                                         Because
    Obeying his belly he struck at the laws.

    His belly?

                Oh, well, he was starving, my boy --
    A state in which, doubtless, there's little of joy.
    No bite had he eaten for days, and his cry
    Was "Bread!" ever "Bread!"

                                What's the matter with pie?

    With little to wear, he had nothing to sell;
    To beg was unlawful -- improper as well.

    Why didn't he work?

                         He would even have done that,
    But men said:  "Get out!" and the State remarked:  "Scat!"
    I mention these incidents merely to show
    That the vengeance he took was uncommonly low.
    Revenge, at the best, is the act of a Siou,
    But for trifles --

                        Pray what did bad Mendicant do?

    Stole two loaves of bread to replenish his lack
    And tuck out the belly that clung to his back.

    Is that _all_ father dear?

                                There's little to tell:
    They sent him to jail, and they'll send him to -- well,
    The company's better than here we can boast,
    And there's --

                    Bread for the needy, dear father?

                                                       Um -- toast.
