The Greek that is translated as «come after me» or «follow me» in English is translated in Guhu-Samane as «will tie my back.»
«Come after» caused «puzzlement [because] since to ‘come after’ means either to ‘follow’ or ‘chase’, and since the context has symbolic talk, it probably means to ‘follow’ but who can say? [But the idiom] ‘whoever will tie my back’ pictures people who, as they travel in the dark night, tie a rope from the leader to the ones following so they will not lose the trail or fall from a cliff, and although not all see the original implications, it is graphic.»
