42.

 He says the same to Eustochium: "Read assiduously and learn as much as you can. Let sleep find you holding your Bible, and when your head nods let it be resting on the sacred page."[⁷²]

When he sent Eustochium the epitaph he had composed for her mother Paula, he especially praised that holy woman for having so wholeheartedly devoted herself and her daughter to Bible study that she knew the Bible through and through, and had committed it to memory. He continues:
I will tell you another thing about her, though evil-disposed people may cavil at it: she determined to learn Hebrew, a language which I myself, with immense labor and toil from my youth upwards, have only partly learned, and which I even now dare not cease studying lest it should quit me. But Paula learned it, and so well that she could chant the Psalms in Hebrew, and could speak it, too, without any trace of a Latin accent. We can see the same thing even now in her daughter Eustochium.[⁷³]
