The WORD unleashed

James 3:14 - But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.
15  This wisdom descendeth not from above, but is earthly, sensual, devilish.

Ephesians 4:31 - Let all bitterness, and wrath, and anger, and clamor, and evil speaking, be put away from you, with all malice:

Romans 3:12 - They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
13  Their throat is an open sepulcher; with their tongues they have used deceit; the poison of asps is under their lips:
14  Whose mouth is full of cursing and bitterness:

Proverbs 17:25 - A foolish son is a grief to his father, and bitterness to her that bore him.

Romans 12:19 - Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.

Colossians 3:19 - Husbands, love your wives, and be not bitter against them.

Proverbs 14:10 - The heart knoweth his own bitterness; and a stranger doth not intermeddle with his joy.

Hebrews 12:15 - 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;

1 Samuel 1:10 - And she was in bitterness of soul, and prayed unto the LORD, and wept sore.
11  And she vowed a vow, and said, O LORD of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the LORD all the days of his life, and there shall no razor come upon his head.

Lamentations 3:15 - He hath filled me with bitterness, he hath made me drunken with wormwood.
16  He hath also broken my teeth with gravel stones, he hath covered me with ashes.
17 And thou hast removed my soul far off from peace: I forgot prosperity.
18  And I said, My strength and my hope is perished from the LORD:
19  Remembering mine affliction and my misery, the wormwood and the gall.
20  My soul hath them still in remembrance, and is humbled in me.
21  This I recall to my mind, therefore have I hope.
