I really like this thread.
Obviously Avraham (his dedication and love for Hashem), Moshe (the greatest prophet that ever lived), David Hamelech (I wish Yisrael had another king that could fill even a tenth of his shoes)...
But I have to admit that I really like Shlomo Hamelech even though it didn't end so well. I relate to him the most and not just because it's my Hebrew name. I always felt that wisdom was much more valuable than money and it made a huge impact on me when I was very young.
He wrote Kohelet (Ecclesiastes), Mishlei (Proverbs), Shir Hashirim (Song of Songs), and he was a great warrior, a musician, and a poet. Plus he carried out his father's dream and built the Beit HaMikdash and that's exactly what I would like to see happen today, G-d willing.
Let kindness and truth never leave you; tie them around your neck; write them on the tablet of your heart -Mishlei 3:3
Every wise woman builds her house; the foolish one destroys it with her own hands. -Mishlei 14:1
He was so deep and his life was full of such meaning.
