Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;
Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
For I perceive that thou art in the gall of bitterness, and in the bond of iniquity.
But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
Whose mouth is full of cursing and bitterness:
Therefore I will not refrain my mouth; I will speak in the anguish of my spirit; I will complain in the bitterness of my soul.
Be ye angry, and sin not: let not the sun go down upon your wrath:
Follow peace with all men, and holiness, without which no man shall see the Lord:
A foolish son is a grief to his father, and bitterness to her that bare him.
Behold, for peace I had great bitterness: but thou hast in love to my soul delivered it from the pit of corruption: for thou hast cast all my sins behind thy back.
1 Samuel 30:6
And David was greatly distressed; for the people spake of stoning him, because the soul of all the people was grieved, every man for his sons and for his daughters: but David encouraged himself in the LORD his God.
My soul is weary of my life; I will leave my complaint upon myself; I will speak in the bitterness of my soul.
And when Esau heard the words of his father, he cried with a great and exceeding bitter cry, and said unto his father, Bless me, even me also, O my father.
