Psalm 2 · a question people ask
"Today I have become your father" (2:7). What day does it mean?
In the psalm the words are the decree the LORD spoke to the one he calls "my son" (Psalm 2:7), and the psalm doesn't name the day. The New Testament quotes the words three times, each for its own point. Paul, in the synagogue at Antioch (Acts 13:14-16), sets them beside the resurrection: "God has fulfilled this to us, their children, in that he raised up Jesus. As it is also written in the second psalm" (Acts 13:33). Hebrews quotes them of the Son, who became "as much better than the angels as the more excellent name he has inherited is better than theirs" (Hebrews 1:4-5). And Hebrews quotes them again of his call as high priest: "So also Christ didn’t glorify himself to be made a high priest, but it was he who said to him" (Hebrews 5:5). None of these verses explains today further, and these notes don't either.
The verses
“I will tell of the decree: The LORD said to me, “You are my son. Today I have become your father.”
“But they, passing on from Perga, came to Antioch of Pisidia. They went into the synagogue on the Sabbath day and sat down. After the reading of the law and the prophets, the rulers of the synagogue sent to them, saying, “Brothers, if you have any word of exhortation for the people, speak.” Paul stood up, and gesturing with his hand said, “Men of Israel, and you who fear God, listen.”
“that God has fulfilled this to us, their children, in that he raised up Jesus. As it is also written in the second psalm, ‘You are my Son. Today I have become your father.’”
“having become as much better than the angels as the more excellent name he has inherited is better than theirs. For to which of the angels did he say at any time, “You are my Son. Today I have become your father?” and again, “I will be to him a Father, and he will be to me a Son?””
