The old agreement {\cf2\super [10]} (the law) that brought death was written with words on stone. {\cf2\super [11]} It came with \{God’s\} glory. The face of Moses {\cf2\super [12]} was so bright with glory that the people of Israel (the Jews) could not continue looking at his face. And that glory later disappeared.
So what was the law {\cf2\super [39]} for? The law was given to show the wrong things people do. The law would continue until the special Descendant of Abraham came. This is the Descendant mentioned in the promise. \{The promise came directly from God.\} But the law was given through angels. The angels used \{Moses for\} a mediator {\cf2\super [40]} to give the law to people.
This true story makes a picture for us. The two women are like the two agreements (covenants) between God and his people. One agreement is \{the law that God made\} on Mount Sinai. {\cf2\super [55]} The people who are under this agreement are like slaves. The mother named Hagar is like that agreement.
{Moses said,} “The Lord gave these commands to all of you when you were together there at the mountain. The Lord spoke with a loud voice that came from the fire, the cloud, and the thick darkness. After he gave us these commands, he didn’t say any more. He wrote his words on two stone tablets and gave them to me.
