“He who exalts himself shall be humbled; and he who humbles himself shall be exalted.”

"Definition of a Gentleman" http://xroads.virginia.edu/~CAP/LEE/gentdef.html, a memorandum found in his papers after his death, as quoted in Lee the American (1912) by Gamaliel Bradford, p. 233
Context: The forbearing use of power does not only form a touchstone, but the manner in which an individual enjoys certain advantages over others is a test of a true gentleman.
The power which the strong have over the weak, the employer over the employed, the educated over the unlettered, the experienced over the confiding, even the clever over the silly — the forbearing or inoffensive use of all this power or authority, or a total abstinence from it when the case admits it, will show the gentleman in a plain light.
The gentleman does not needlessly and unnecessarily remind an offender of a wrong he may have committed against him. He cannot only forgive, he can forget; and he strives for that nobleness of self and mildness of character which imparts sufficient strength to let the past be but the past. A true man of honor feels humbled himself when he cannot help humbling others.

Meister Eckhart’s Sermons (1909)
Context: When man humbles himself, God cannot restrain His mercy; He must come down and pour His grace into the humble man, and He gives Himself most of all, and all at once, to the least of all. It is essential to God to give, for His essence is His goodness and His goodness is His love. Love is the root of all joy and sorrow. Slavish fear of God is to be put away. The right fear is the fear of losing God. If the earth flee downward from heaven, it finds heaven beneath it; if it flee upward, it comes again to heaven. The earth cannot flee from heaven: whether it flee up or down, the heaven rains its influence upon it, and stamps its impress upon it, and makes it fruitful, whether it be willing or not. Thus doth God with men: whoever thinketh to escape Him, flies into His bosom, for every corner is open to Him. God brings forth His Son in thee, whether thou likest it or not, whether thou sleepest or wakest; God worketh His own will. That man is unaware of it, is man's fault, for his taste is so spoilt by feeding on earthly things that he cannot relish God's love. If we had love to God, we should relish God, and all His works; we should receive all things from God, and work the same works as He worketh.
