²⁵ Whenever you ^[a]stand praying, if you have anything against anyone, forgive him [drop the issue, let it go], so that your Father who is in heaven will also forgive you your transgressions and wrongdoings [against Him and others]. ^26 [b][“But if you do not forgive, neither will your Father in heaven forgive your transgressions.”]
