Virtually, every Karaite respects Rabbi Abraham ibn Ezra. He lived in the 12th Century, and he is arguably the greatest of the classical Rabbanite peshatist (plain meaning) commentators. I have even quoted him in my talks. One of the reasons he is such a good peshatist is because he was combatting the then-thriving Karaite movement, which espoused peshat above all.
In addition to writing commentaries, ibn Ezra also penned numerous poems – the most famous of which is Ki Eshmera Shabbat. It is well known that the poem wound up in Karaite prayer books. It is less well-known that the Karaites modified the poem to remove anti-Karaite rhetoric. And it is even less well-known that the version that appears in Karaite prayer book still appears to have anti-Karaite polemics.
