apple of his eye
Deuteronomy 32:10
32:10 apple of his eye. There are five references in the Bible to “the apple of the eye,” meaning the pupil of the eye, and speaking of something of great value to the owner. Three times (Deuteronomy 32:10, Lamentations 2:18 and Zechariah 2:8), the phrase refers to Israel as God’s choice permission. It is also applied to individual believers (Psalm 17:7-8). Perhaps most significantly, it is applied to the written word of God (Proverbs 7:1-2).
