'Back' in the Bible

When Jesus had crossed back over in the boat to the other side, a great multitude was gathered to him; and he was by the sea.

If anyone asks you, 'Why are you doing this?' say, 'The Lord needs him;' and immediately he will send him back here."

Let him who is in the field not return back to take his cloak.

for it was very big. Looking up, they saw that the stone was rolled back.
