In case you missed it last year, I had a whole series of posts about Yishmael. In honor of Parshat Hayei Sarah, I'll link to them this year:
- Yishmael and Zimah
- The Root of the Arab-Israeli Conflict by Rav Eliyahu Shlesinger
- Galut Yishmael by Rav Yoel Schwartz
- On Yishmaels' age at death
- CosmicX's latest post.
