No. The only thing said to be allegorical in the Bible is in Gal 4:21-31. We know Sarah and Hagar were literal, historical people. However there are many more from the OT. The most famous one is probably Nathan's confrontation with David about his adultery with Bathsheba and murder of Uriah---2 Sam 12:1-7.
IMO most if not all of the OT is an allegory of either the work of Jesus or the life of a Christian or both. I have just stated a study of what may be the most beautify allegory of the work of Christ in the entire Bible. If you are interested, ask me in about a week.
Parables have the same goal(teach a spiritual truth) but must be interpreted differently. Usually a parable takes something we are familiar with---sowing a field. In them we must determine what the different elements symbolize, and they must be consistent throughout the Bible. There is one exception.
Jesus give us this principle by interpreting his first 2 parables for us---The parables of the sower.
In them he makes the substitutions for us: All the people of His day would have seen a farmer sowing seed in his field. The sower is Jesus(Mt 13:37), the field is the world(Mt 13:38), the good seed is the sons of the kingdom, Christians.
Here is the one exception, which I don't see as an exception---In Luke 8:11, the seed is the word of God. There is a theorem that says, "things equal to the same thing are equal to each other." That means Christians are the word of God. This is reinforced in 2 Cor 3:2-3.
Hope this helps.
Thank you. I always enjoy hearing the insights and perspective of my Christian brothers and sisters regardless of differences. I am a Baha'i and of the Holy Bible, Abdu'l-Baha had this to say:
THIS book is the Holy Book of God, of celestial Inspiration. It is the Bible of Salvation, the Noble Gospel. It is the mystery of the Kingdom and its light. It is the Divine Bounty, the sign of the guidance of God.
