34. ye had compassion on me in my bonds--The oldest manuscripts and versions omit "me," and read, "Ye both sympathized with those in bonds (answering to the last clause of He 10:33; compare He 13:3, 23; 6:10), and accepted (so the Greek is translated in He 11:35) with joy (Jas 1:2; joy in tribulations, as exercising faith and other graces, Ro 5:3; and the pledge of the coming glory, Mt 5:12) the plundering of your (own) goods (answering to the first clause of He 10:33)."

in yourselves--The oldest manuscripts omit "in": translate, "knowing that ye have for (or 'to') yourselves."

better--a heavenly (He 11:16).

enduring--not liable to spoiling.

substance--possession: peculiarly our own, if we will not cast away our birthright.
