When ye stand praying Standing was their usual posture when they prayed. Forgive, if ye have aught against any If you expect your prayers should prevail with God, you must take care to offer them in love as well as in faith; and, as you have offended the Majesty of heaven by many provocations, if you expect forgiveness from him, you must forgive your fellow-creatures if you have any matter of complaint against any of them. See notes on Matthew 6:14-15; Matthew 18:23-35.
