At last it pressed on me, that if I admitted morals to rest on an independent basis, it was dishonest to shut my eyes to any apparent collisions of morality with the Scriptures.

A very notorious and decisive instance is that of Jael .-- Sisera, when beaten in battle, fled to the tent of his friend Heber, and was there warmly welcomed by Jael, Heber's wife.
After she had refreshed him with food, and lulled him to sleep, she killed him by driving a nail into his temples; and for this deed, (which now-a-days would be called a perfidious murder,) the prophetess Deborah, in an inspired psalm, pronounces Jael to be "blessed above women," and glorifies her act by an elaborate description of its atrocity.

As soon as I felt that I was bound to pass a moral judgment on this, I saw that as regards the Old Testament the battle was already lost.

Many other things, indeed, instantly rose in full power upon me, especially the command to Abraham to slay his son.

Paul and James agree in extolling Abraham as the pattern of faith; James and the author of the Epistle to the Hebrews specify the sacrifice of Isaac as a firstrate fruit of faith: yet if the voice of morality is allowed to be heard, Abraham was (in heart and intention) not less guilty than those who sacrificed their children to Molech.
Thus at length it appeared, that I must choose between two courses.
