Samyutta Nikaya
There are many references to rebirth in the Early Buddhist texts (henceforth EBTs). Some key suttas which discuss rebirth include "Mahakammavibhanga Sutta" (Majjhima Nikaya "MN" 136); "Upali Sutta" (MN 56); "Kukkuravatika Sutta" (MN 57); "Moliyasivaka Sutta" (Samyutta Nikaya "SN" 36.21); and "Sankha Sutta" (SN 42.8).
