John 20:26
Eight days later [i.e., the following Sunday], Jesus' disciples were inside [the house] again, [but this time] Thomas was with them. The doors were [still] closed when Jesus [suddenly] stood among them [See note on verse 19] and said, "May there be peace in your hearts."
John 20:19
So, when it was evening on that day, [which was] the first day of the week [i.e., Sunday] and the doors [of someone's house], where the disciples were gathered, were closed [i.e., probably locked] for fear of the Jewish authorities, Jesus came and stood among them. [Note: Probably Jesus passed through the closed door miraculously]. He said to them, "May there be peace in your hearts."
John 14:27
I leave you with peace; I give you my peace. I am not giving you peace like the world gives. Do not allow your hearts to be upset or afraid.
John 20:21
Jesus said to them again, "May there be peace in your hearts. Just as the Father has sent me, so I am sending you."
Matthew 17:1
And after six days [had passed], Jesus took Peter, James, and his brother John aside and went up into a high mountain [i.e., an unidentified mountain nearby].
Luke 9:28
And it happened about eight days after Jesus said these things that He took Peter, John and James with Him and went up in the mountain to pray. [Note: This was probably Mt. Tabor, which was nearby].
