Hi,there

How often is subject-verb inversion used with "shall" and "will"?

For example, in the Bible, Genesis 2:24 says "Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh"... Therefore shall a man..."... And 2 Corinthians 12:8-9 says:  "This thing I besought the Lord thrice, that it might depart from me. <sup class="versenum" style="color: rgb(0, 0, 0); font-family: Times;"> </sup>And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me....

Is that still common? "Therefore shall a man..." and "therefore will I rather glory..."? Is it wrong to say "Therefore a man shall leave..." and "Therefore I will rather glory in..."? Do I have to place "shall/will" before I? 

Thank you
