Servants

Leviticus 25:55 LXX
οτι εμοι οι υιοι ισραηλ οικεται παιδεσ μου ουτοι εισιν ουσ εξηγαγον εκ γησ αιγυπτου εγω κυριοσ ο θεοσ υμων

Leviticus 25:55 NIV
for the Israelites belong to me as servants. They are my servants, whom I brought out of Egypt. I am the Lord your God.

The Greek for servants implies a child within the household with a distinct purpose. God brought His people out of Egypt, sometimes referred to as His son. The law was given and became the schoolmaster to make the people ready, to train them in the way of the Lord.

At the right moment, Jesus came showing the purpose of the law. He fulfilled the law, provided the way for us to do the same, and ransomed His own to the freedom of sons and daughters.

Who did this and why?

"I am the Lord your God."
