4 Maccabees 13:23

²¹and having been brought forth at equal intervals, and having sucked milk from the same fountains, hence their brotherly souls are reared up lovingly together;

²²and increase the more powerfully by reason of this simultaneous rearing, and by daily intercourse, and by other education, and exercise in the law of God.

— 4 Maccabees 13:23 —

²⁴For being educated in the same law, and practicing the same virtues, and reared up in a just course of life, they increased this harmony with each other.

²⁵For a like ardor for what is right and honorable increased their fellow feeling toward each other.
