I am looking for a CRON expression which should run every 2 weeks on Thursday. As an e.g. if I execute the JOB on June 24th Thursday , next execution should be on July 8th THU, next is JULY 22nd THU, AUGUST 5th and so on.

AFAIK, cron jobs don't like scheduling something every X days where X is greater than 7. You will need to cheat a bit by either scheduling something to happen on the first and third Thursday of a month, such as 0 0 1-7,15-21 * 3 as suggested by this answer over on ServerFault.

Alternatively, you can change the script of the job itself to only execute on odd-numbered weeks as suggested by other answers on that same post above. For example:

0 0 * * 4 [ `expr \`date +\%V\` \% 2` -eq 0 ] && echo "execute script"

This cron job will run every Thursday, but the script will only run the command after the && if the current week index is divisible by 2.
