Interesting: King James I believed Matthew 6:13 was Scripture+called it "canonical". He called Jerome's Latin Vulgate [J.L.V] "euill [evil]"+noted J.L.V omitted 2nd half of Matthew 6:13 (Source:Pages 595, 596)

Despite King James I said Robert Stephanus mentioned a Greek codex did not have Matthew 6:13, above photos of Stephanus 1551 & Beza 1598 TRs show Robert Stephanus copied Matthew 6:13's words from other ancient Greek codices he had into his Textus Receptus editions, & so did Beza in his TRs-
a great example of God's preservation of the Scriptures' words, including Greek New Testament, throughout history.
To anyone wondering, both Robert Stephanus' 1551 Textus Receptus/TR edition+Theodore Beza's 1598 TR edition HAVE/CONTAIN all Matthew 6:13, so Stephanus & King James I were not wrong here

All of Matthew 6:13 is inspired, preserved Scripture
1611 KJB: And lead vs not into temptation, but deliuer vs from euill: For thine is the kingdome, and the power, and the glory, for euer, Amen.
