Real Widows Pray
1Tim 5:5 Now she who is really a widow, and left alone, trusts in God and continues in supplications and prayers night and day.
For these next dozen verses Paul gets very particular of the type of widow which the church should officially support.
An example of a widow who reflects this condition is Anna of whom it is written, "Now there was one, Anna, a prophetess, the daughter of Phanuel, of the tribe of Asher. She was of a great age, and had lived with a husband seven years from her virginity; and this woman was a widow of about eighty-four years, who did not depart from the temple, but served God with fastings and prayers night and day." Luke 2:36,37
More generally this gives the poor and otherwise afflicted an idea of what God expects of them. They are to be involved in talking with God night and day. Anna understood that.
