Tit for tit and tat for tat ... meaning of

Thank you for adding the link …

Yes, now I remember reading it in a small library in El Cajon, California 1984 I think it was.

It was with a lot of other old poems and it was 500bc I never could remember if it was ad or bc
till now and it was attributed to a Greek poet. (his name I have forgotten)

but I never forgot the message of echo, almost like going up and down the steps
of a temple

How the greek language came up with a ryhme using tit for tat this I do not know
