Means "when." Features in Sanhedrin 43a in the Talmud, during an apocryphal description of the death of Yeshua the Nazarene, as one of his five disciples. This may have been the way early Rabbinic Jews understood the Christian apostle Matthew. Matai uses a pun with his name alluding to Psalm 42:3, saying, "“When {matai} shall I come and appear before God?" and the judges of the Sanhedrin respond with Psalm 41:6 - "“When {matai} shall he die, and his name perish?” before sentencing him to death.
