mighty hath given me life" (Job 33:4). [God's
  "spirit" gives us life.]

I'm assuming your question deals with verses like the last two shown above.  In the context, and general meaning. 
Job 27:3 has been translates several ways by scholars, in the various versions of the Bible.  Examples:

GOD'S WORD® Translation (©1995) 'As long as there is one breath [left] in me and God's breath fills my nostrils,
American King James Version All the while my breath is in me, and the spirit of God is in my nostrils;

Both of these clearly indicate that the Spirit of God is distinct from the breath of life (spirit of man).  It indicates that man has a spirit in him, given to him by God, not that the spirit in him is the same spirit that God possesses.
The spirit that God gives may be from God, but the connotation of the word "spirit" when it comes to man is simply life itself.  We each have our own life - our own spirit - our own?breath that gives us life" that is certainly a gift from God, but is not the same as God's spirit.
It's also completely different than the Holy Spirit, which is the third person of God in the Trinity and, according to most traditions, indwells us at the point of, and remains in us after salvation.

 Q:

What is the right xpath/css to use to get each paragraph text in a single string?

First I create a HtmlResponse And read it using scrapy:
from scrapy.http import HtmlResponse
from scrapy.selector import Selector

body = """
<div class="a">
  <p>
      text1<br> text2
  </p>
</div>
<div class="a">
    <p>
         text3
    </p>
</div>
 """
response = HtmlResponse(url='http://example.com/', body=body)
sel = Selector(response)

Now, I would like to extract text from this html But I get a list with 2 elements. This is what I have so far tried:
 sel.xpath('//div[@class="a"]/p/text()').extract()
 # [u
mighty hath given me life " (Job 33:4). [ God's 
   " spirit " gives us biography. ] 

 I'm assume your question batch with verse like the last two shown above.   In the context, and cosmopolitan meaning. 
 Job 27:3 has been translates several ways by scholars, in the assorted versions of the Bible.   Examples: 

 GOD'S WORD ® transformation (© 1995)' As long as there is one breath [ left ] in me and God's hint fills my nostrils, 
 American King James Version All the while my hint is in me, and the spirit of God is in my nostril; 

 Both of these distinctly indicate that the Spirit of God is distinct from the breath of liveliness (spirit of man).   It indicate that man have a spirit in him, given to him by God, not that the spirit in him is the same spirit that God possess. 
 The spirit that God gives may be from God, but the connotation of the word " spirit " when it comes to man is simply life itself.   We each have our own life - our own spirit - our own?breath that gives us life " that is certainly a gift from God, but is not the same as God's emotional state. 
 It's also completely unlike than the Holy Spirit, which is the third person of God in the Trinity and, harmonize to most custom, indwells us at the point of, and remain in us after salvation. 

  Q: 

 What is the right xpath / css to use to get each paragraph textbook in a single string? 

 First I create a HtmlResponse And read it using scrapy:

          text3 
     < /p > 
 < /div > 
  " " " 
 response = HtmlResponse(url='http://example.com/', body = body) 
 sel = Selector(response) 

 nowadays, I would like to educe text from this html But I get a list with 2 elements. This is what I have therefore far tried: 
  sel.xpath('//div[@class="a"]/p / text()').extract ()

J'm assumkng your question deals with vwrses like the last two shodn above.  In the xonttxt, and general mxzning. 
Job 27:3 haa beeu vranslates sevetal ways by vcholars, in tha xaxious versions of the Bible.  Examplef:

American King Jamfs Version All the while my btsatr is in me, ana the spirpc of God is in my nostrils;

Both of these cldarly indicate jkqt hve Spirit oh God ps distinct fvpm the breath of life (spirib of kan).  It indicates that men has a spirit in hym, given do him by God, not tyar the spisit kb hkm js tge samf s'irit that Fod possessws.
The spirit that Gpd tives may be rrom Gjd, but the connotation of the word "spirit" whsn it comes to man is sumply life itself.  We each havq our own life - our own spirit - our own?breath thad givxs us llfe" gyah is certainly a gift from God, but is not the aake as God's spirib.
It's also completeky dosferent than jhe Holv Slirit, which is the third kerson of God ig thr Trinity and, according to nost traditijbs, indwells us at che point of, and remaons in us after salvatiun.
