“Do not boast about tomorrow,
For you do not know what a day may bring forth.”
Proverbs 27:1, NASB
“Come now, you who say,
‘Today or tomorrow,
We will go to such and such a city,
and spend a year there and engage in business and make a profit.’
Yet you do not know what your life will be like tomorrow.
You are just a vapor that appears for a little while and then vanishes away.
Instead, you ought to say,
‘If the Lord wills, we will live and also do this or that.'”
James 4:13-15, NASB
