{Whensoever ye stand} (hotan st(886b)ete). Late form of
present indicative st(886b)(935c), from perfect stem hest(886b)a. In LXX.
Note use of hotan as in  11:19 . Jesus does not mean by the use
of "stand" here to teach that this is the only proper attitude in
prayer. {That your Father also may forgive you} (hina kai ho
pat(8872) aph(8869) humin). Evidently God's willingness to forgive is
limited by our willingness to forgive others. This is a solemn
thought for all who pray. Recall the words of Jesus in  Mt
6:12,14f .
