Bede, on Prov 5:18

“Let thy vein be blessed, and rejoice with the wife of thy youth:”

“"Let your fountain be blessed," etc. Maintain such temperance with the woman you married in your youth, even in old age, that by faithful chastity you may rightly gain a blessing in your offspring. "A loving doe, a graceful fawn." Let her always be your beloved spouse, who, like a doe that avoids serpents, shuns harlots and drives them away from her home. Let a son be born from her, and he himself be a very strict lover of chastity.”
