Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end. ~ John 13:1 KJV

[Now] Before the Passover Feast began, Jesus knew (was fully aware) that the time had come for Him to leave this world and return to the Father. And as He had loved those who were His own in the world, He loved them to the last and to the highest degree. ~ John 13:1 AMP
