Hebrews 13:3 Meaning and Commentary

Hebrews 13:3

Remember them that are in bonds
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;
outward afflictions of body, distress for want of temporal mercies, food and raiment, and persecution by enemies; or spiritual adversity, as the prevailings of corruptions, and particularly unbelief, the hidings of God's face, and the temptations of Satan.

As being yourselves also in the body;
as if in their bodies, enduring the same things; or as being afflicted in the body with diseases, necessities, and persecutions; or as being in the body, the church, of which these afflicted ones are a part, and therefore should have a fellow feeling with them; or rather as being in this world, in the flesh, or in a body and state subject to the like adversities, temporal and spiritual.

Hebrews 13:3 In-Context

1 Let brotherly love remain;
2 of the hospitality be not forgetful, for through this unawares certain did entertain messengers;
3 be mindful of those in bonds, as having been bound with them, of those maltreated, as also yourselves being in the body;
4 honourable [is] the marriage in all, and the bed undefiled, and whoremongers and adulterers God shall judge.
5 Without covetousness the behaviour, being content with the things present, for He hath said, `No, I will not leave, no, nor forsake thee,'
