Reference: Eunice
American
The mother of Timothy and daughter of Lois; she was a Jewess though her husband was a Greek, Ac 16:1; 2Ti 1:5. She transmitted to her son the lessons of truth she herself had received from a pious mother; and Paul, on his arrival at Lystra, found them rooted and grounded in the truth as it is in Christ.

Timothy's mother. "In her unfeigned faith made its dwelling" (enookesen); a believing Jewess, but wedded to Timothy's father a Greek, i.e. a pagan (Ac 16:1). It is an undesigned coincidence, and so a mark of truth, that in the history just as in the epistle the faith of the mother alone is mentioned, no notice is taken of the father. Probably converted at Paul's first visit to Lystra (Ac 14:6-7). The one parent's faith sanctified the child (1Co 7:14). The Scriptures were her chief teaching to Timothy from childhood (2Ti 3:15). Lois, her pious mother and Timothy's grandmother, had doubtless taught herself in them: hereditary piety.

EUNICE, the mother of Timothy, who was a Jewess by birth, but married to a Greek, Timothy's father, 2Ti 1:5. Eunice had been converted to Christianity by some other preacher, Ac 16:1-2, and not by St. Paul; for when that Apostle came to Lystra, he found there Eunice and Timothy, already far advanced in grace and virtue.
