The Jewish Isaac Da Costa (1798-1860) lived in Amsterdam and worked as a poet and writer. In 1847 he wrote a moving poem about Hagar and Ishmael.
In a deep way he communicated the hope he had for the descendants of Ishmael in the widest sense. One day they will be free and will voluntarily submit to the descendants of Sarah’s only son Isaac.
What a day that will be!
Parts of the Dutch poem have been translated into English and published by Samuel Zwemer several of his books. They are available here in PDF.
