IV Maccabees 13:20

20 In which these brothers having remained an equal time, and having been formed for the same period, and been increased by the same blood, and having been perfected through the same principle of life,

IV Maccabees 13:20 In-Context

18 And as each one of the brethren was haled away, the rest exclaimed, Disgrace us not, O brother, nor falsify those who died before you.
19 Now you are not ignorant of the charm of brotherhood, which the Divine and all wise Providence hath imparted through fathers to children, and hath engendered through the mother's womb.
20 In which these brothers having remained an equal time, and having been formed for the same period, and been increased by the same blood, and having been perfected through the same principle of life,
21 and having been brought forth at equal intervals, and having sucked milk from the same fountains, hence their brotherly souls are reared up lovingly together;
22 and 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.
