Simeon (Greek: Συμεών) at the Temple is the "just and devout" man of Jerusalem who, according to Luke 2:25–35, met Mary, Joseph, and Jesus as they entered the Temple to fulfill the requirements of the Law of Moses on the 40th day from Jesus' birth, i. e. the presentation of Jesus at the Temple.
According to the Biblical account, the Holy Spirit visited Simeon and revealed to him that he would not die until he had seen the Christ of God.
