'Pupil' in the Bible
The LORD found him in a desert land, in a barren, eerie wilderness. He surrounded, cared for, and guarded him as the pupil of his eye.
Their duties, whether significant or insignificant, whether performed by teacher or pupil alike, were assigned by lottery.
For this is what the LORD of the Heavenly Armies says: "In pursuit of glory I was sent to the nations who plundered you, because whoever injures you injures the pupil of my eye.
