Jews speak about this matter. I will contend myself with briefly mentioning
JOHN CALVIN
from which it might appear that they had lived. Now, the only reason why the children born to the surviving brother, should be reckoned to him who had died, was, that there might be no dry branch in the family; and in this manner they took away the reproach of barrenness. Besides, since the woman is given as a help to the man, when any woman married into a family, she was, in a certain sense, given up to the name of that family. According to this reasoning, Tamar was not altogether free, but was held under an obligation to the house of Judah, to procreate some seed. Now, though this does not proceed from any rule of piety, yet the Lord had impressed it upon the hearts of man as a duty of humanity; as he afterwards commanded it to the Jews in their polity. Hence we infer the malignity of Onan, who envied his brother this honor, and would not allow him, when dead, to obtain the title of father; and this redounds to the dishonor of the whole family. We see that many grant their own sons to their friends for adoption: it was, therefore, an outrageous act of barbarity to deny to his own brother what is given even to strangers.595 Moreover he has not only shortened his brother concerning the right due to him, but he rather spilled seed on the ground than to raise a son in his brother's name.
10. And the thing which he did displeased the LORD. Less neatly the Jews speak about this matter. I will contend myself with briefly mentioning this, as far as the sense of shame allows to discuss it. It is a horrible thing to pour out seed besides the intercourse of man and woman. Deliberately avoiding the intercourse, so that the seed drops on the ground, is double horrible. For this means that one quenches the hope of his family, and kills the son, which could be expected, before he is born. This wickedness is now as severely as is possible condemned by the Spirit, through Moses, that Onan, as it were, through a violent and untimely birth, tore away the seed of his brother out the womb, and as cruel as shamefully has thrown on the earth. Moreover he thus has, as much as was in his power, tried to destroy a part of the human race. When a woman in some way drives away the seed out the womb, through aids, then this is rightly seen as an unforgivable crime. Onan was guilty of a similar crime, by defiling the earth with his seed, so that Tamar would not receive a future inheritor.
11. Then said Judah to Tamar. Moses intimates that Tamar was not at liberty to marry into another family, so long as Judah wished to retain her under his own authority. It is possible that she voluntarily submitted herself to the will of her father-in-law, when she might have refused: but the language seems to mean, that it was according to a received practice, that Tamar should not pass over to another family, except at the will of her father-in-law, as long as there was a successor who might raise up seed by
