Mark 11:25

And when you stand to pray, if you hold anything against another, forgive it, so that your Father in heaven will forgive your trespasses as well.”

Note BYZ and TR include 26 But if you do not forgive, neither will your Father in heaven forgive your trespasses; see Matthew 6:15.

And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses.

Whenever you stand praying, forgive, if you have anything against anyone; so that your Father, who is in heaven, may also forgive you your transgressions.

And whensoever ye stand praying, forgive, if ye have aught against any one; that your Father also who is in heaven may forgive you your trespasses.
