How to add rows at a specific location

I have a text file like this

1  2 0
30  0.7646 0.150 0.400 0.350 0.600 1.000 0.000 
34  0.2354 0.150 0.000 0.350 0.000 1.000 0.000 
79 79 79 10 10 10 12 12 10 10 10 10
1  2 1
30  0.7646 0.150 0.400 0.350 0.600 1.000 0.000 
34  0.2354 0.150 0.000 0.350 0.000 1.000 0.000 
79 79 79 10 10 10 12 12 10 10 10 10

I have a second text file like this

30
31
32

My question is

if the value of first text file matches with value of first column of secong text file then in fist text file where first row third column is 1 (1 2 1) there the line 30 0.7646 0.150 0.400 0.350 0.600 1.000 0.000(because 30 is matching) will add before the last line like 79 79 79 10 10 10 12 12 10 10 10 10

The final text file will be

1  2 0
30  0.7646 0.150 0.400 0.350 0.600 1.000 0.000 
34  0.2354 0.150 0.000 0.350 0.000 1.000 0.000 
79 79 79 10 10 10 12 12 10 10 10 10
1  2 1
30  0.7646 0.150 0.400 0.350 0.600 1.000 0.000 
34  0.2354 0.150 0.000 0.350 0.000 1.000 0.000
 30  0.7646 0.150 0.400 0.350 0.600 1.000 0.000 
79 79 79 10 10 10 12 12 10 10 10 10

Could you please separate the code and filetext from the question statements? It's a bit difficult to understand with everything mixed together.
