Jesus spoke about words, this was his advice:
Mat 5:37 But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
This cuts right to the quick, and exposes motives for the abundance of words.
He made many points with this one statement:
A simple yes or no affirms the truth, or untruth of any matter; which is enough.
It reaffirms the verses before it, to not speak any oaths, because it brings the one who does so into condemnation, which James also tell us in the book of James ch 5.
Jas 5:12 But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and your nay, nay; lest ye fall into condemnation.
Lengthy discourses are seed for exaggeration and untruthfulness, the breeding ground for lying.
The abundance of words can reveal pride.
There can be great beauty and richness in words used in poetry, lyrics of music, teachings, books, exhortations, and when used with skill can benefit mans spirit and soul in many ways, when God is guiding the use of them.
People want to sound intelligent, important, make sure the explanation has been thoroughly enhanced. But, many times the same description could be given very effectively with three words rather than ten.
