²³ This is what the Lord says:
“Let not the wise boast of their wisdom
    or the strong boast of their strength
    or the rich boast of their riches,
²⁴ but let the one who boasts boast about this:
    that they have the understanding to know me,
that I am the Lord, who exercises kindness,
    justice and righteousness on earth,
    for in these I delight,”
declares the Lord.
–Jeremiah 9:23-24 (NIV)–

Do nothing out of selfish ambition or vain conceit. 
Rather, in humility value others above yourselves.
–Philippians 2:3 (NIV)–
