Hebrews 13:3

“Remember them that are in bonds, etc..] Not for criminal actions, or for debt, though such should be remembered, and pity showed them, especially the latter; but such as are in bonds for the sake of Christ, and the Gospel. This has been often the lot of God's people, who should be remembered, by praying for them, sending comfortable letters to them, personally visiting them, and relieving them under their distresses: as bound with them; as if it were so, as if in the same condition, and circumstances; by sympathizing with them; by considering themselves liable to the same bonds; by dealing with them as it would be desirable to be dealt with in the same case: and them which suffer adversity;…”

“Remember--in prayers and acts of kindness. bound with them--by virtue of the unity of the members in the body under one Head, Christ (Co1 12:26). suffer adversity--Greek, "are in evil state." being yourselves also in the body--and so liable to the adversities incident to the natural body, which ought to dispose you the more to sympathize with them, not knowing how soon your own turn of suffering may come. "One experiences adversity almost his whole life, as Jacob; another in youth, as Joseph; another in manhood, as Job; another in old age" [BENGEL].”

“Remember them that are in bonds - All who are “bound;” whether prisoners of war; captives in dungeons; those detained in custody for trial; those who are imprisoned for righteousness’ sake, or those held in slavery. The word used here will include all instances where “bonds, shackles, chains were ever used.” Perhaps there is an immediate allusion to their fellow-Christians who were suffering imprisonment on account of their religion, of whom there were doubtless many at that time, but the “principle” will apply to every case of those who are imprisoned or oppressed. The word “remember” implies more than that we are merely to “think” of them; compare Exodus 20:8; Ecclesiastes 12:1. It means…”

“Remember - In your prayers, and by your help. Them that are in bonds, as being bound with them - Seeing ye are members one of another. And them that suffer, as being yourselves in the body - And consequently liable to the same. Hebrews 13:4”

“13:3 Remember those in prison: Prisoners often depended on family members and friends for their most basic needs. Christians were challenged to provide comfort, food, prayer, and other necessities for those imprisoned because of their faith (13:18-19; Matt 25:36; Col 4:18; 2 Tim 1:16).”
