'Merely' in the Bible

Jesus replied, “Woman, believe Me, a time is coming [when God’s kingdom comes] when you will worship the Father neither on this mountain nor in Jerusalem.

But the hired man [who merely serves for wages], who is neither the shepherd nor the owner of the sheep, when he sees the wolf coming, deserts the flock and runs away; and the wolf snatches the sheep and scatters them.

The man runs because he is a hired hand [who serves only for wages] and is not concerned about the [safety of the] sheep.
