Just and righteous fathers get drunk and impregnate their daughters.
Behold now, I have two daughters which have not known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes. Genesis 19:8
Come, let us make our father drink wine, and we will lie with him, that we may preserve seed of our father. And they made their father drink wine that night: and the firstborn went in, and lay with her father; and he perceived not when she lay down, nor when she arose. Behold, I lay yesternight with my father: let us make him drink wine this night also; and go thou in, and lie with him, that we may preserve seed of our father. And they made their father drink wine that night also: and the younger arose, and lay with him; and he perceived not when she lay down, nor when she arose. Thus were both the daughters of Lot with child by their father. Genesis 19:32-36
Just Lot ... that righteous man. 2 Peter 2:7-8
A good father abandons his children, if his wife (and God) asks him to.
Wherefore she (Sarah) said unto Abraham, Cast out this bondwoman (Hagar) and her son (Ishmael) ... And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice. ... And Abraham ... took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child and sent her away: and she departed, and wandered in the wilderness. Genesis 21:10-14
A good father is willing to kill his children, if God asks him to.
And he said, Take now thy son, thine only son Isaac, whom thou lovest, and ... offer him there for a burnt offering.... And Abraham stretched forth his hand, and took the knife to slay his son. Genesis 22:2,10
A good father watches in silence as God burns his children to death.
And Nadab and Abihu, the sons of Aaron ... offered strange fire before the LORD, which he commanded them not. And there went out fire from the LORD, and devoured them, and they died before the LORD. .... And Aaron held his peace. Leviticus 10:1-3
A good father offers his daughter as a burnt offering to God, if he promised God that he'd do it in a vow.
Then the Spirit of the LORD came upon Jephthah.... And Jephthah vowed a vow unto the LORD, and said, If thou shalt without fail deliver the children of Ammon into mine hands, Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the LORD's, and I will offer it up for a burnt offering. ...
So Jephthah passed over unto the children of Ammon to fight against them; and the LORD delivered them into his hands. And he smote them ... with a very great slaughter. ...
And Jephthah came to Mizpeh unto his house, and, behold, his daughter came out to meet him with timbrels and with dances.... And ... when he saw her... said, Alas, my daughter! ... I have opened my mouth unto the LORD, and I cannot go back. And she said unto him ... Let this thing be done for me: let me alone two months, that I may go up and down upon the mountains, and bewail my virginity, I and my fellows. ... And it came to pass at the end of two months, that she returned unto her father, who did with her according to his vow which he had vowed. Judges 11:29-39
