Candidate passages:
Ahitophel (; "Brother of Insipidity", or "Impiety") was a counselor of King David and a man greatly renowned for his sagacity.
At the time of Absalom's revolt he deserted David (Psalm.
41:9; 55:12-14) and espoused the cause of Absalom (2 Samuel 15:12).
David sent his old friend Hushai back to Absalom, in order that he might counteract the counsel of Ahitophel (2 Sam.
15:31-37).
Ahitophel, seeing that his good advice against David had not been followed due to Hushai's influence, correctly predicted that the revolt would fail.
He then left the camp of Absalom at once.
He returned to Giloh, his native place, and after arranging his worldly affairs, hanged himself, and was buried in the sepulcher of his fathers (2 Sam.
17:1-23).
A man named Ahitophel is also mentioned in 2 Samuel 23:34, and he is said to be the father of Eliam.
Since 2 Samuel 11:3 notes that Eliam is the father of Bathsheba, some scholars suggest that the Ahitophel of 2 Samuel 15 may in fact be Bathsheba's grandfather.
Levenson and Halpern, for example, note that "the narrator is sufficiently subtle (or guileless) to have Bathsheba's grandfather... instigate the exaction of YHWH's pound of flesh," as Nathan's curse in 2 Samuel 12:11 comes to fruition. 
The traditionally accepted identification of the model is of Rembrandt's partner Hendrickje Stoffels, who would have been 28 at the time of the painting.
Sluijter has proposed otherwise, stating that the likeness is of an ideal type used by Rembrandt over a long period.
Assuming Stoffels as the model, medical researchers have observed deformity in the left breast, and have offered various hypotheses including breast cancer, abscess due to tuberculosis and lactation mastitis following an unsuccessful pregnancy.
The diagnosis of breast cancer is unlikely, given that Stoffels lived for another nine years.
The look of sorrow in the subject's face has been interpreted as evidence of Stoffels' illness, pregnancy (she gave birth to a daughter in October 1654), Rembrandt's difficulties with the Church stemming from his cohabitation with Stoffels, and the artist's impending bankruptcy.
An alternative hypothesis for the model's identity has suggested that Stoffels' head was placed on the body of another model, which is consistent with the result derived from that Bathsheba's head had been repainted. 
Bathsheba Bowers (June 4, 1671 – 1718) was an American Quaker author and preacher.
Her only surviving work is the spiritual autobiography "An Alarm Sounded to Prepare the Inhabitants of the World to Meet the Lord in the Way of His Judgments" (1709).
Bowers was one of twelve children of Quakers Benanuel Bowers and Elizabeth Dunster Bowers, the niece of Henry Dunster, first president of Harvard University.
Her parents were from England and immigrated to America, settling in Charlestown, Massachusetts, where Bowers was born and raised.
Anti-Quaker persecution prompted the Bowers family to send their four eldest daughters to Philadelphia, which had a large Quaker population.
Bowers never married, though her sisters did, and the diary of Ann Bolton née Curtis, the daughter of Bowers' sister Elizabeth who lived with the Bowers family for a brief time, provides what little biographical information is known of Bowers outside of her own writing.
In Philadelphia, Bowers was noted for her eccentricity.
Near a spring, she built a small home that the locals called "Bathsheba's Bower" or "Bathsheba's folly" and lived as a recluse.
She cultivated her garden and adopted the principles of vegetarian Thomas Tryon.
She professed Quakerism but had a deep argumentative and independent streak.
According to Bolton, Bowers was "so Wild in her Notions it was hard to find out what religion she really was of".
"An Alarm" was likely published in New York by Quaker printer William Bradford in 1709.
In the work, she presents her life as a series of tests designed by God for her to overcome and outlines her spiritual progress overcoming them.
While "An Alarm" adheres to many of the conventions of Quaker spiritual autobiographies, its tone is that of what one critic describes as "a woman always emotionally on edge".
Bowers published an unknown number of other works, including a biography.
The public response, if any, to her work is also unknown.
She received no attention from scholars until the late 20th century, especially after her inclusion in the "Heath Anthology of American Literature" (1990).
When she was thirty five, Bowers moved to South Carolina, where there was a growing Quaker population.
According to Bolton, Bowers believed she could not die.
Bolton wrote of an Indian attack:...the Indians Early one morning surprised the place - killed and took Prisoners several in the house adjoining to her.
Yet she moved not out of her Bed, but when two Men offered their assistance to carry her away, she said Providence would protect her, and indeed so it provided at the time, for those two men no doubt by the Direction of providence took her in her Bed for she could not rise, conveyed her into their Boat and carried her away in Safety tho' the Indians pursued and shot after them.
Bowers, however, eventually did die in South Carolina at the age of 46. 
Grabarz's unusual surname comes from Grabarz's grandfather, Ernst Karl Grabarz (1934–2001), who was Polish. 
In March 1778, Joshua Spooner, a wealthy farmer in Brookfield, was beaten to death and his body stuffed down a well.
Four people were hanged for the crime: two British soldiers, a young Continental soldier, and Spooner's wife, Bathsheba, who was charged with instigating the murder.
She was 32 years old and five months pregnant when executed.
Newspapers described the case as "the most extraordinary crime ever perpetrated in New England.
"Bathsheba was the mother of three young children, and in her own words felt "an utter aversion" for her husband, who was known to be an abusive drunk.
A year before the murder, she took in and nursed a sixteen-year-old Continental soldier who was returning from a year's enlistment under George Washington.
The two became lovers and conceived a child.
Divorces were all but impossible for women at that time, and adulteresses were stripped to the waist and publicly whipped.
Bathsheba's pregnancy occasioned a series of desperate plots to murder her husband, finally brought to fruition with the aid of two British deserters from General John Burgoyne's defeated army.
As the daughter of the state's most prominent and despised Loyalist, Bathsheba bore the brunt of the political, cultural, and gender prejudices of her day.
When she sought a stay of execution to deliver her baby, the Massachusetts Council rejected her petition, and she was promptly hanged before a crowd of 5,000 spectators.
