13Come now, you who say, "Today or tomorrow we will go into such and such a town and spend a year there and trade and get gain"; 14whereas you do not know about tomorrow. What is your life? For you are a mist that appears for a little time and then vanishes. 15Instead you ought to say, "If the Lord wills, we shall live and we shall do this or that." 16As it is, you boast in your arrogance. All such boasting is evil. 17Whoever knows what is right to do and fails to do it, for him it is sin.
Psalms 49:2-3, 6-11
1Hear this, all peoples! Give ear, all inhabitants of the world, 2both low and high, rich and poor together! 5Why should I fear in times of trouble, when the iniquity of my persecutors surrounds me, 6men who trust in their wealth and boast of the abundance of their riches? 7Truly no man can ransom himself, or give to God the price of his life, 8for the ransom of his life is costly, and can never suffice, 9that he should continue to live on for ever, and never see the Pit. 10Yea, he shall see that even the wise die, the fool and the stupid alike must perish and leave their wealth to others.
38John said to him, "Teacher, we saw a man casting out demons in your name, and we forbade him, because he was not following us." 39But Jesus said, "Do not forbid him; for no one who does a mighty work in my name will be able soon after to speak evil of me. 40For he that is not against us is for us.
