Galatians 4:24-25

24These two women are like pictures of two agreements that God made with his people. Hagar is like the agreement that God made on Sinai mountain. That agreement causes people to become slaves.

25Hagar is like a picture of Sinai mountain in Arabia. Also, she is like the city of Jerusalem here on earth now, because that city and its people are slaves under the authority of God's Law.
