C. F. Keil and Franz Delitzsch on 1 Samuel 14:27

1Sa 14:27

But Jonathan, who had not heard his father’s oath, dipped (in the heat of pursuit, that he might not have to stop) the point of his staff in the new honey, and put it to his mouth, “and his eyes became bright;” his lost strength, which is reflected in the eye, having been brought back by this invigorating taste. The Chethibh תראנה is probably to be read תּראנה, the eyes became seeing, received their power of vision again. The Masoretes have substituted as the Keri תּארנה, from אור, to become bright, according to 1Sa 14:29; and this is probably the correct reading, as the letters might easily be transposed.
