Note 28 at 1 Tim. 5:11: Paul reasons that younger widows are not able to contain their sexual desires as well as older widows; therefore, are more likely to violate their oath to the church about remaining single (see note 30 at this v.). He encourages the younger widows to remarry and raise families.

Note 29 at 1 Tim. 5:11: Remember that Paul is talking about refusing to accept total financial responsibility for these younger widows. He is not against showing love and benevolence towards young widows. He says it's better for them to marry and have families than to become celibate and devoted solely to the church and ministry.

Note 30 at 1 Tim. 5:11: There certainly isn't anything wrong with a widow, young or old, marrying, and there is no reason to pronounce damnation on anyone who does. Paul said in this same letter that it was a doctrine of devils to forbid people to marry (1 Tim. 4:3). He certainly wasn't going against his own instructions in this same letter.

Apparently, there was a formal commitment required from the women who entered this number of widows that were taken care of by the church, that they would not remarry, but devote themselves to godly living and serving others, perhaps as deaconesses. Certainly this was voluntary, but once it was done, it was a solemn oath not to be taken lightly.

If they violated this commitment, they were subject to the judgment of the church and removed from the list of widows the church supported (see note 31 at v. 12).
