From a letter she wrote February 2, 1863 we learn that Frances was donating copies of her book Canticles to help with the cotton famine.
The book was her translation of and commentary on The Song of Solomon in the Bible, and it departed some from the Authorized Version. She wanted to be sure that William Caddell, to whom she was sending the copies and who would be selling them, was free from any doubt of the correctness of the translation.
He had asked her how she explained the phrase, "His lips are like lilies," which she answered in this letter. Her answer was, "not in colour but in form, as we talk of the lip of a vase or anything that laps over. We talk of the lip of a cup or other vessel, referring to the form in pottery, gold or silver cups; if you look in the concordance you will find it so."
What delights me in Frances' work is her devotion to detail. She believed the Bible to be totally inspired by God, and thus every word important. And I love how her art and poetry contributed to and derived from her love of the Bible.
I've heard people claim that the Bible is full of contradictions. If those people examined it carefully, they would find that this assumption is untrue. The more minutely one studies it, the more beautifully it all fits together.
