John 5:13

He that was healed [ι α θ ε ι ς]. Compare ver. 10, and note the different word for healing. See references there.

Who it was [τ ι ς ε σ τ ι ν]. The present tense, who it is.

Had conveyed Himself away [ε ξ ε ν ε υ σ ε ν]. The verb means, literally, to turn the head aside, in order to avoid something. Hence, generally, to retire or withdraw. Only here in the New Testament.
