In Deuteronomy 15 v12-18 we read that if a person had fallen on hard times,he could sell himself as a slave for six years to someone.It was God who laid out the terms,he said on the seventh year they had to be released.It was not an oppressive thing it was a means of helping people through hard times. When they were released the master of the slave had to give the slave a generous farewell present. Raymond Brown writes,'The servant must be allowed to leave his masters house in style''.It was a very fair system,there was no abuse involved,but say the person did not want to leave,because he loved his master, he had to submit himself to a simple ceremony of being taken to a door and having his ear pierced a sign of willing submission. Steve Croft wrote a song applying it to our relationship with God,it was called ,' Pierce my ear.'
'Pierce my ear,oh, Lord, my God
Take me to your door this day
I will serve no other God
Lord ,I'm here to stay.
For you have paid the price for me
With your blood You ransomed me
A free man I'll never be.'
