'East to west' in the Bible

For like lightning that shoots from east to west, so will be the arrival of the Son of man.

while they went out and preached everywhere, the Lord working with them and confirming the word by the miracles that endorsed it. (b) But they gave Peter and his companions a brief account of all these injunctions. And, after that, Jesus himself sent out by means of them from east to west the sacred and imperishable message of eternal salvation.
