Devour widows’ houses - The word “houses” is used here to denote “property” or possessions of any kind. You take away or get possession of the property of widows by improper arts and pretences. This was done in two ways:
1. They claimed a very exact knowledge of the law and a perfect observance of it. They pretended to extraordinary justice toward the poor, friendship for the distressed, and willingness to aid those who were in embarrassed circumstances. They thus induced “widows” and poor people to commit the management of their property to them as guardians and executors, and then took advantage of them and defrauded them.
2. They put on the appearance of great sanctity, and induced many conscientious but credulous women to give them much, under pretence of devoting it to religious purposes.
Long prayer - Their prayers are said to have been often three hours in length. One rule among them, says Lightfoot, was to meditate an hour, then pray an hour, and then meditate another hour - all of which was included in their “long prayers or devotions.”
Damnation - Condemnation. The word here probably refers to future punishment. It does not always, however. It means, frequently, no more than “condemnation,” or the divine disapprobation of a certain course of conduct, as in 1 Corinthians 11:29; “He that eateth and drinketh unworthily, eateth and drinketh “damnation” to himself;” that is, he that eateth and drinketh in an unworthy manner disorderly, not with reverence - is guilty, and his conduct will be disapproved or condemned by God referring solely to the impropriety of the manner of partaking of the Lord’s supper, and not at all to the worthiness or unworthiness of the person. See the notes at that place. Compare Romans 14:23.
For a pretence - For appearance or show; in order that they might the better defraud poor people. They would not be condemned for “making” long prayers, but because they did it with an evil design. Public prayers should, however, be short, and always to the point. A man praying in a Sunday school should pray for the school, and, usually, not for everything else.
