Replace based on values in a file

[WJSwan]

I have a file containing records with 4 values, eg:
1,Genesis,Gen,Gen
2,Eksodus,Eks,Exo
3,Levitikus,Lev,Lev
4,Numeri,Num,Num
5,Deuteronomium,Deut,Deu
6,Josua,Jos,Jos
7,Rigters,Rig,Jdg
8,Rut,Rut,Rth
9,1 Samuel,1 Sam,1Sa

I need to read these into an array and I then need to read a second file and in each record of this file replace occurrences of the 3rd field in the first file (Gen, Eks, Lev, Num, Deut etc.) with the first field (1,2,3, etc. followed by a fullstop, eg 1., 2., 3.).

So if the second has a record reading:

Ps. 19:3; Num 3:1........
This needs to be replaced by:
19.19:3; 4.3:1.....

How would I achieve this? I have just started learning Python, so I am really a novice.
