John Gill

And these things give in charge,.... Concerning rebuking persons of a different age and sex, and concerning the maintenance of widows; and particularly that children provide for their parents when helpless; and that widows trust in God, and give themselves to prayer and supplication, and not live in sin: that they may be blameless; before men, and in the view of the world, and not be chargeable with any notorious crime; though none are without blame in themselves, and before God, but as considered in Christ Jesus.
