She is mentioned only in 2 Timothy 1:5, where the author writes to Timothy, "I am reminded of your sincere faith, a faith that dwelt first in your grandmother Lois and your mother Eunice and now, I am sure, dwells in you as well."(ESV) Many commentators have also connected Eunice to 2 Tim. 3:15, where Timothy is reminded "how from childhood you have been acquainted with the sacred writings".(ESV) Albert Barnes, for example, says, "The mother of Timothy was a pious Hebrewess, and regarded it as one of the duties of her religion to train her son in the careful knowledge of the word of God."
