Excel Table reorganization

Hi experts,

I have a table in excel where i have three columns named "First","Mid","End". Each column is filled with data like in the table below

First Mid End
2 18 3
3 7 8
3 11 9
8 15 4
9 19 14
14 21 20
14 25 4
20 28 4

what I want to do is to create numerical paths using the above table using the random number (example let’s say I selected 2) so starting from 2, I will pick the first three element from the same row which is = 2 18 3 then I will take the last element from this path (3) and look for the same number in the first column on the table and continue the path 2, 18,3,7,8 (omitting the repetition of 3). Likewise I want to list down all the possible paths that I can have using the above table.
Example of a result for the above table is

2,18,3,7,8,15,4
2,18,3,11,9,19,14,21,20,28,4
2,18,3,11,9,19,14,25,4

Can someone please help me on the coding or formula that could help me get the result displayed above? Please note the number of rows contained in the table could vary. But for every row of data all three columns will have data in that row.

Your expertise on this matter will be greatly appreciated.
