The Generous Eye, with Brad H. Young: Matthew 6:22-23

In Matthew 6, is Jesus talking about "healthy" and "unhealthy" eyes, as translations sometimes have it (e.g., NIV, ESV, NLT), or is the Greek expression an idiom that Jewish listeners would have readily understood in another way? Dr. Brad H. Young is Emeritus Professor in Judaic Christian Studies with an emphasis in Biblical Literature at Oral Roberts University Graduate School of Theology and Ministry, and Professor at Jerusalem Seminary. Among other things, he has published Jesus the Jewish Theologian and The Parables: Jewish Tradition and Christian Interpretation.
