A.T. Robertson Commentary Mark 14:32

"And they come unto a place which was named Gethsemane: and he saith unto his disciples, Sit ye here, while I pray." — Mark 14:32 (ASV)

Which was named (ου το ονομα). Literally, "whose name was." On Gethsemane see on Mt 26:36.

While I pray (εως προσευξωμα). Aorist subjunctive with εως really with purpose involved, a common idiom. Matthew adds "go yonder" (απελθων εκε).
