'In Me' in the Bible

and after giving thanks [for it], He broke it [in pieces] and said, "This represents my [physical] body, which is [to be given] for you. [Continue to] do this in memory of me."

In the same way [He took] the cup also, after supper, and said, "This cup [i.e., its contents] represents the New Agreement [ratified] by my blood. [Continue to] do this, whenever you people drink from it, in memory of me."
