'Back' in the Bible

Paul, an Apostle (not from men, and not through man, but through Jesus Christ, and God the Father, who made him come back from the dead),

I did not go up to Jerusalem to those who had become apostles before me; instead I went to Arabia and came back to Damascus.

for before that certain came from James, he ate with those of the nations; but when they came, he drew back and separated himself, fearing those of the circumcision;

But now, since you know God, or rather have become known by God, how can you turn back again to the weak and bankrupt elemental forces? Do you want to be enslaved to them all over again?

Be not tricked; God is not made sport of: for whatever seed a man puts in, that will he get back as grain.
