I am trying to arouse your sincere intention by reminding you that you should remember the words spoken in the past by the holy prophets, and the commandment of the Lord and Saviour spoken through your apostles. (vs 1b-2)
As Jesus was walking along, he saw a man called Matthew sitting at the tax booth; and he said to him, ‘Follow me.’ And he got up and followed him. (v. 9)
And all of you must clothe yourselves with humility in your dealings with one another, for 'God opposes the proud, but gives grace to the humble.' (v. 5)
