Hi, and glad you're here.
Jesus said "I know my sheep, and my sheep know me".
My best explanation would be, it wasn't their turn yet. They had not yet been drawn to Him, so they would be reconciled to Him - yet. Jesus didn't reveal Himself to most at that time - only the chosen then, as He does still in this age after the cross. Then all the rest in the next age.
Blessings.
