Calling of Saint Matthew depicts the story from the Gospel of Matthew (Matthew 9:9): “Jesus saw a man named Matthew at his seat in the custom house, and said to him, “Follow me”, and Matthew rose and followed Him.” Caravaggio depicts Matthew the tax collector sitting at a table with four other men. Jesus Christ and Saint Peter have entered the room, and Jesus is pointing at Matthew. A beam of light illuminates the faces of the men at the table who are looking at Jesus Christ.
7 Therefore, as the Holy Spirit says,
“Today, if you hear his voice,
8 do not harden your hearts as in the rebellion,
as on the day of testing in the wilderness,
9 where your ancestors put me to the test,
though they had seen my works 10 for forty years.
Therefore I was angry with that generation,
and I said, ‘They always go astray in their hearts,
and they have not known my ways.’
11 As in my anger I swore,
‘They will not enter my rest.’”
12 Take care, brothers and sisters, that none of you may have an evil, unbelieving heart that turns away from the living God. 13 But exhort one another every day, as long as it is called “today,” so that none of you may be hardened by the deceitfulness of sin.
