IV Maccabees 13:26

26 For it acting along with religion, made their brotherly feeling more desirable to them.

IV Maccabees 13:26 In-Context

24 For being educated in the same law, and practising the same virtues, and reared up in a just course of life, they increased this harmony with each other.
25 For a like ardour for what is right and honourable increased their fellow-feeling towards each other.
26 For it acting along with religion, made their brotherly feeling more desirable to them.
27 And yet, although nature and intercourse and virtuous morals increased their brotherly love those who were left endured to behold their brethren, who were ill-used for their religion, tortured even unto death.
